NFL Nation reporters provide preseason predictions -- from rookies who will win position battles, to players who will break out, to injured veterans who are finally healthy and ready to succeed -- for the teams they cover.
Coach Gary Kubiak will be asked about the quarterback competition at least once a day until a decision is made.
In the face of that, Kubiak will not rush the decision, and he will not waver in his stock answer that he is confident the Broncos "will pick the right guy." After the early work in camp, however, it's clear Mark Sanchez will have to lose the job before he is passed on the depth chart. Despite Trevor Siemian's quality work behind center, it looks like only a significant stumble in the preseason would keep Sanchez from starting the Broncos' regular-season opener. -- Jeff Legwold
Safety Eric Berry won't sign until the preseason is underway.
The Chiefs and their franchise player failed to agree on the terms of a multi-year contract by the July 15 deadline, which made Berry's only option to play the season to sign the team's obligatory, one-year offer worth about $10.8 million. Berry, who overcame cancer to have one of his best seasons in 2015, has too many good reasons to play this year, so it's likely he will eventually sign the contract. However, unhappiness about not reaching a long-term deal will delay his signing until after the Aug. 13 preseason opener. -- Adam Teicher
Watson, a former second-round draft pick who is coming back from a torn Achilles tendon suffered last preseason, was getting the first-team reps in offseason workouts, while Howard, who suffered a season-ending knee injury in Week 14 last season, was breathing down his neck. This should be the most entertaining position battle of camp. -- Paul Gutierrez
Wide receiver Tyrell Williams will steal the show in training camp.
Fans rightly will focus on emerging star Keenan Allen, but Williams, a second-year pro out of Western Oregon, came on late last season and should emerge as a deep threat for the Chargers, along with Travis Benjamin. The retirement of Malcom Floyd means San Diego must find playmakers, and the 6-foot-4, 205-pound wideout will get a chance to take Floyd's place. -- Eric D. Williams
Wide receiver Breshad Perriman will return before training camp ends and be ready to start the regular season.
Cue the eye roll now. Perriman proved to be a slow healer with a knee injury last season, when he missed his entire rookie year, but he was expected to miss only eight weeks after partially spraining his ACL this offseason. He is showing progress in his rehab and should be ready by the middle of August, which would give him enough time to get up to speed for the regular season. Perriman, a first-round pick in 2015, has a chance to be an impact playmaker early in the season. -- Jamison Hensley
Tyler Boyd will electrify Bengals fans who have the chance to watch training camp practices.
After an impressive spring, No. 83 will be one player to keep an eye on. The second-round rookie was dubbed "Cadillac" by veteran cornerback Adam Jones during organized team activities for the way the wide receiver seemed to seamlessly hum into a second and third gear while running routes. Jones was complementing the smooth nature with which the receiver ran. We'll be paying close attention to how Boyd performs in one-on-one situations throughout camp, particularly when matched up with Jones and fellow rookie William Jackson III. -- Coley Harvey
Isaiah Crowell will reward the faith shown in him by coach Hue Jackson.
Crowell has looked quick, active and in shape in the early part of training camp. His cuts are crisp, his running fluid and he has also made nice catches out of the backfield. Hue Jackson did not bring in a high draft pick or free agent RB, which indicates he believes Crowell can be productive. "He has some really unquestionable ability," Jackson said. With Jackson's faith and if Crowell maintains what he starts, he could have a much better season than many expected. -- Pat McManamon
Little-known slot receiver Eli Rogers will emerge as a key player in the Steelers' receiver rotation.
In the process, Rogers will take reps from either Sammie Coates or Darrius Heyward-Bey. Rogers is the only true slot receiver on the roster, and the team is pleased with his progress. -- Jeremy Fowler
Jadeveon Clowney will complete his first full training camp and preseason slate.
Clowney, who has 4.5 career sacks, has been injury-riddled during his first two seasons in the NFL. He has had a concussion, groin injury, torn meniscus, ankle injury, back injury and Lisfranc sprain. He and the Texans are hoping his slew of bad luck is over. -- Tania Ganguli
The Colts thought about selecting Ferguson in the middle rounds of April's draft but passed because of more pressing needs. They got lucky when they were able to sign the running back out of Illinois as an undrafted free agent. Indianapolis wants to lightened Gore's workload because he's 33 years old and last season had 227 more carries than his next closest teammate. The Colts look at Ferguson as a dual-threat back. -- Mike Wells
Joeckel, the No. 2 overall pick in 2013, has been average at best in three seasons. The Jaguars really like free-agent addition Beachum's quick feet, and that allows him to better handle speed off the edge, which is Joeckel's biggest problem. -- Mike DiRocco
Marcus Mariota will throw some interceptions in training camp.
In his first training camp last year, Mariota went 13 practices and threw 230 passes before he was intercepted. There was great national debate about its importance. It certainly indicated how cleanly he practiced. As Mariota works with some new receivers and against a secondary that includes more ball-hawking types, a long interception-less practice streak is far less likely. -- Paul Kuharsky
Hold the fireworks: The Bills will be boring this summer.
I hesitate to predict this because the Bills, especially under Rex Ryan, have been a magnet for bizarre developments in recent years. But that unlike last year, the Bills don't have a quarterback battle (Tyrod Taylor is their unquestioned starter), their first-round draft pick won't be on the field (Shaq Lawson is out until likely October after shoulder surgery), and their top two offensive playmakers, LeSean McCoy and Sammy Watkins, will be kept in protective bubbles as much as possible during camp. I think fans will buy less into Rex Ryan's hype this August than they did last preseason, and Buffalo's faithful will wait until September to see if this team can back it up on the field. -- Mike Rodak
Receiver DeVante Parker will be the star of training camp.
The 2015 first-round pick finished last season on a high note and will carry that momentum into this summer. The Dolphins were cautious with Parker in the spring, in an effort to make sure he stays healthy, but Parker will shine once the coaching staff turns him loose. -- James Walker
Joe Thuney will win the starting job at left guard.
The third-round draft choice from NC State worked with the first unit for most of spring camps and is primarily competing against fourth-year player Josh Kline and second-year player Shaq Mason for the top spot. Returning O-line coach Dante Scarnecchia seems to like Thuney quite a bit. -- Mike Reiss
The Jets will go against conventional NFL wisdom and keep four quarterbacks on the 53-man roster.
The QBs: Ryan Fitzpatrick, Geno Smith, Bryce Petty and rookie Christian Hackenberg. It'll be cumbersome, for sure, but they have to manage short- and long-term goals. Fitzpatrick and Smith, both of whom will be free agents after the season, are the short-term guys. Petty and Hackenberg provide long-term options. The downside: The development of Petty and Hackenberg will be stunted because they won't get enough practice reps. -- Rich Cimini
First-round pick Robert Nkemdiche will drop jaws throughout training camp.
Nkemdiche is starting training camp with a sprained ankle, but when he's at full strength, he'll show just how talented, quick and powerful he is -- and he'll make a lot of teams regret passing on him in April's draft. The Cardinals, however, will bring him along slowly, making sure the injury doesn't linger. -- Josh Weinfuss
Two rookie fourth-round picks will earn prominent roles in the offense.
While most eyes will be on No. 1 overall pick Jared Goff's progression, keep an eye on wide receiver Pharoh Cooper and tight end Tyler Higbee. Cooper might already be the team's best true slot receiver and should find himself getting plenty of work during camp, even if it isn't in a starting role. The same goes for Higbee, who has a chance to emerge as the team's best pass-catching tight end to complement do-everything Lance Kendricks. -- Nick Wagoner
A healthy Carlos Hyde will emerge as the focal point of Chip Kelly's offense.
Although most of the talk will be about the quarterback competition between Colin Kaepernick and Blaine Gabbert, Hyde's progression is worth watching. The tempo of Kelly's offense often leads some to mistake it for a pass-heavy operation, but Kelly's system works best when the running game is the foundation. When the Eagles finished second in yards per game in 2013, they led the league in rushing by more than 16 yards per game. As long as Hyde is back to full strength -- and the Niners are cautious with him -- he should leave camp positioned to step into a starring role. -- Nick Wagoner
The Tyler Lockett buzz will reach epic levels.
The second-year wide receiver is probably the favorite to be the star of this year's camp. He had an excellent rookie season and put in work with quarterback Russell Wilson this offseason. Don't be surprised if "Wilson connected with Lockett deep" becomes a daily observation from those in attendance at training camp. The hype on Lockett will be especially meaningful if he's able to make plays downfield against Richard Sherman. -- Sheil Kapadia
Mark it down: Wide receiver Kevin White will shred Chicago's secondary.
White, who missed his entire rookie season because of injury, excelled in the Bears' offseason program against the club's suspect secondary. Expect the No. 7 overall pick in the 2015 draft to thrive once again in training camp, where defensive backs are at a disadvantage because they cannot hit offensive players. Big, fast and strong, White should dominate in 7-on-7 or full-team drills without the fear of getting hit. Now, whether White's performance translates to the regular season is another story, but in camp, expect him to look elite. -- Jeff Dickerson
Matthew Stafford, again, looks good in the preseason.
This has been a common theme the past few years, and it hasn't always translated to regular-season success. But Stafford has a good rapport with offensive coordinator Jim Bob Cooter and has a familiarity there that can't be overlooked. Stafford is going to be adjusting to new offensive pieces -- most recently Anquan Boldin -- but he'll continue carrying momentum from the end of last season, when he played like a top-10 quarterback. Whether that carries to the regular season is -- and always has been -- the question. -- Michael Rothstein
The Packers won't play Jordy Nelson in any preseason games.
After experiencing what he called "a hiccup" with his left knee while rehabbing his surgically repaired right knee this summer, Nelson will be lucky to even practice before the regular-season opener at Jacksonville. Even quarterback Aaron Rodgers seemed prepared for that possibility when he said, "We're going to need a little bit of time -- not necessarily game reps -- but just some reps in practice" to be ready for Week 1. -- Rob Demovsky
The Vikings will give Adrian Peterson more work.
Why more training camp work for a veteran such as Peterson? To help him become more compatible with Teddy Bridgewater in shotgun sets. They'd prefer to not use Peterson in preseason games, but coach Mike Zimmer admitted after last season that he should have done more to get Peterson acclimated with the Vikings' changing offense when the running back returned from his 2014 suspension. The Vikings will put their time to good use this year, as they seek to improve the fit between their 31-year-old running back and 23-year-old quarterback. -- Ben Goessling
Rookie De'Vondre Campbell will solidify his role as the starting weakside linebacker.
The fourth-round pick started camp strongly by showing his speed in coverage. Now he has to make sure he gets a full grasp of the defense. But athletically, no one should challenge him at the spot. -- Vaughn McClure
The Panthers are looking for a replacement for Pro Bowl cornerback Josh Norman, and what better player to replace him than the player who took over Norman's No. 24? Bradberry, at 6-foot-1, is about the same size as Norman. The rookie second-round pick is more disciplined than Norman was as a rookie. Bradberry worked with the first team throughout the offseason, and I expect him to remain there through camp. -- David Newton
Sheldon Rankins will earn a leading role.
The Saints do a lot of rotating at defensive tackle, so it's no big deal that veteran Nick Fairley has been working with the starters ahead of rookie Rankins so far. Chances are, they'll spend a lot of time together in the lineup. But if Rankins, the No. 12 overall pick in April's draft, lives up to his lofty potential once the pads come on Saturday and once preseason games begin, it might be hard to take him off the field, especially for a defense that desperately needs to get more disruptive. -- Mike Triplett
Rookie defensive end Noah Spence will make a strong case for the starting job.
In the first practice in training camp, while lining up with the second-team defense, Spence blew past veteran right tackle Gosder Cherilus. He affords the Bucs some flexibility with their fronts because he can dip back into coverage too. Plus, he and Robert Ayers make a great tandem when Ayers lines up inside, where he had about half of his sacks with the Giants. With Jacquies Smith at left defensive end and Pro Bowler Gerald McCoy in his usual spot, that has the makings of a scary pass rush. -- Jenna Laine
Cornerback Morris Claiborne will make it through a training camp healthy.
The former top-10 pick has not been able to do that in his first four seasons with the Cowboys, thanks to wrist, knee and hamstring injuries. Claiborne, who re-signed with the Cowboys on a one-year deal, is coming off his best offseason in part because he has been healthy. He was able to focus on football and not rehab for the first time. There's this prediction too: Not only will Claiborne make it through camp, but also he will be a starter in Week 1 against the Giants. -- Todd Archer
The annually injury-riddled Giants will remain healthy this summer.
Call this a hunch, but already the results of a new strength and conditioning program appear to be paying off. The Giants had only three players on the physically unable to perform list (Damon Harrison, J.T. Thomas and Jay Bromley) when practices began, and none was dealing with a long-term injury. Something tells me this trend will continue throughout the summer and the Giants will enter the season one of league's healthier teams. It would be much-needed because of their lack of depth on the roster. -- Jordan Raanan
Cornerback Eric Rowe will work his way back into the Eagles' plans.
The former second-round pick slid down the depth chart during OTAs and wasn't mentioned by coaches as training camp began. But Rowe explained that he had trouble with one specific technique that he hadn't been asked to do in college at Utah or with the Eagles as a rookie. Once he gets that worked out, his size and athleticism should make him a factor in Jim Schwartz's defense. -- Phil Sheridan
The Redskins' starting cornerbacks will emerge as one of the best duos in the NFL.
The continued improvement of third-year player Bashaud Breeland makes this possible. Breeland is a smart player who has always studied the game and adjusted, but now he's playing with Josh Norman, who can help his game develop even more. Breeland has already incorporated various techniques from Norman, including how to use his hands at the line of scrimmage. -- John Keim
