ESPN Fantasy's Mike Clay breaks down the fantasy impact of each skill-position pick from the first round of the NFL draft on Thursday.

Check back on Friday for his live takes on Rounds 2 and 3 to see what sort of fantasy value we can expect from those players in 2017 and beyond.

No. 2: QB Mitchell Trubisky to Chicago Bears

The Bears pulled off the night's first shocker, trading up to second overall and selecting North Carolina's Trubisky. The former Tar Heel didn't spend much time as the starter during his time at North Carolina but impressed by completing 304 of 446 attempts (68 percent) for 3,748 yards, 30 touchdowns and 6 interceptions last season. He was off target on 7.3 percent of his throws, which was lowest among quarterbacks who attended the combine. Trubisky is considered raw but has a good, accurate arm and will add fantasy production with his legs. Chicago signed Mike Glennon to a three-year, $45 million contract during free agency, so he remains the favorite to start Week 1. Of course, the rookie will get a shot to compete. The Bears' offensive supporting cast around Trubisky is suspect, at best, so it's likely to take some time until he makes a big fantasy impact. He can be ignored in 12-team season-long drafts.

Rookie-season projection: 82-of-131, 883 yards, 5 TDs, 4 INTs

No. 4: RB Leonard Fournette to Jacksonville Jaguars

The Jaguars selected LSU's Fournette with the fourth overall pick. Fournette is about as big as you'll find at the position. He's 6-foot, 240 pounds with 9 1/4-inch hands, 32-inch arms and 4.51-second wheels in the 40-yard dash. An ankle injury limited Fournette to seven games last season, but he was dominant during his first two years with the team. He has terrific upside as a rusher, especially in the scoring department, but he doesn't figure to do much as a pass-catcher. Chris Ivory and T.J. Yeldon remain on the roster, but Fournette is a near lock to slide in as the team's feature back. Expect the Jaguars to lean heavier on the run than they did in the past to keep the ball out of Blake Bortles' hands, while also relying on their terrific defense. Fournette should immediately be viewed as an RB2 and can be upgraded slightly in non-PPR formats.

Rookie-season projection: 265 carries, 1,182 yards, 8 TDs; 29 receptions, 218 yards, 1 TD

No. 5: WR Corey Davis to Tennessee Titans

The Titans shored up their wide receiver position by snagging Western Michigan's Davis with the fifth pick. Davis didn't do much at the combine, so he rode his collegiate production and interviews to a top-five pick. Davis is 6-foot-3, 209 pounds and can work inside and out. He'll be busy as a deep threat and near the goal line. The Titans had one of the league's biggest needs at the position, and Davis immediately joins the starting lineup opposite veteran Rishard Matthews. The Titans' offense is extremely run-heavy, which will certainly limit Davis' short-term fantasy prospects, but the combination of his talent and opportunity land him in the flex discussion.

Rookie-season projection: 59 receptions, 774 yards, 6 TDs

No. 7: WR Mike Williams to Los Angeles Chargers

The Chargers' crowded group of offensive skill-position players just added yet another asset to the pile with Clemson's Williams. He figures to immediately join Tyrell Williams on the perimeter, with Keenan Allen working the slot in the Philip Rivers-led offense. The 6-foot-3, 218-pounder also will need to fend off Antonio Gates, Hunter Henry, Travis Benjamin and Dontrelle Inman for snaps and targets. Williams doesn't have a ton of speed in his arsenal, but he's a big, tough possession receiver who can work at all levels and at the goal line. This offense won't be short on passing yards and touchdowns, but Williams figures to struggle for big-time target numbers in such a crowded situation. He's a shaky flex play as a rookie, but he has big-time dynasty upside.

Rookie-season projection: 57 receptions, 696 yards, 5 TDs

No. 8: RB Christian McCaffrey to Carolina Panthers

Cam Newton has a new counterpart in the Panthers' backfield with Stanford's McCaffrey. He was about as good as it gets during his time in red and white -- and at April's combine. He produced a whopping 2,327 all-purpose yards last year. Super elusive and athletic, McCaffrey dominated the vertical, three-cone short shuttle and 60-yard dash in Indianapolis. He's only 20 years old and will immediately contribute as a rusher, receiver and returner. Jonathan Stewart had his contract extended through 2018 but will clearly settle into a reduced role. It's actually a good one-two punch, with McCaffrey more of a scatback than a strong asset in short yardage. McCaffrey should immediately be viewed as an RB2, especially in PPR formats, and there's room for more if Carolina features him in the pass game.

Rookie-season projection: 196 carries, 880 yards, 6 TDs; 49 receptions, 454 yards, 2 TDs

No. 9: WR John Ross to Cincinnati Bengals

The Bengals simply couldn't pass up Ross' record-breaking speed. The Washington product ran a 4.22-second 40-yard dash at April's combine and now joins the Bengals' offense as a speed complement to superstar A.J. Green. With Brandon LaFell, slot man Tyler Boyd and tight end Tyler Eifert also in the mix, quarterback Andy Dalton won't be short on weapons in 2017 and beyond. Ross is obviously going to be a lid-lifter in the pros and can help out as a returner. He has serious medical concerns, but Cincinnati obviously felt comfortable with the 21-year-old in the first round. Ross is 5-foot-10, 188 pounds, so like the man he's often compared to -- DeSean Jackson -- he may never be a good source of touchdowns and high-end receptions totals. That means more value in non-PPR leagues. He'll be very reliant on big plays in Cincinnati's suddenly crowded offense in 2017.

Rookie-season projection: 51 receptions, 714 yards, 4 TDs

No. 10: QB Patrick Mahomes to Kansas City Chiefs

Andy Reid has decided it's time to look to the future at quarterback. The Chiefs traded up for Mahomes, and he will immediately compete for starting duties with Alex Smith, who will soon turn 33. The Texas Tech product has consistency and accuracy issues but is a terrific athlete with a huge arm. Mahomes tossed 41 touchdown passes and 10 interceptions last season and showed well in most efficiency categories. Mahomes is likely to open his career as clipboard holder, but Smith's leash is obviously shorter than ever. At the very least, he'll be a good bet to make some late-season starts if Kansas City falls out of the playoff mix.

Rookie-season projection: 5 games, 86-of-140, 803 yards, 5 TDs, 3 INTs

No. 12: QB Deshaun Watson to Houston Texans

Twelve picks down and eight are of the offensive variety. The Texans traded up with Cleveland -- which has now passed on Carson Wentz, Mitchell Trubisky and Watson -- to snag their likely Week 1 starter. Clemson's FBS championship-winning quarterback shouldn't have much trouble brushing Tom Savage aside. Watson is a terrific athlete with a big arm and a ton of pedigree. He's 6-foot-4, 221 pounds and came in better than average in every combine drill. Watson threw for 41 touchdowns but was picked off 17 times last year. His 84.9 QBR was tops among quarterbacks who attended the combine. Watson is the best bet among the three rookie quarterbacks chosen thus far to start in Week 1. His legs will give him added fantasy value, and it certainly helps that he'll be surrounded by a quality group of targets in DeAndre Hopkins, Will Fuller V, Braxton Miller, Lamar Miller and C.J. Fiedorowicz. Watson has some QB2 appeal but will obviously be risky as a rookie.

Rookie-season projection: 319-of-535, 3,630 yards, 20 TDs, 16 INTs; 59 carries, 300 yards, 2 TDs

No. 19: TE O.J. Howard to Tampa Bay Buccaneers

The draft's top tight end is headed to Tampa Bay. Howard was underused during his time in Alabama, totaling only 45 receptions for 595 yards and three touchdowns last season. Howard is 6-foot-6, 251 pounds with exceptional speed, quickness, toughness and athleticism. He crushed it at the combine, posting the quickest times in the three-cone short shuttle and 60-yard shuttle. Howard is also an outstanding blocker, which all but assures him a big role right out of the gate. Of course, rookie tight ends rarely provide much fantasy value, and Cameron Brate was terrific as a receiver last season. That said, Howard should be viewed as no more than a fringe TE2 at the start. He's a top-end dynasty tight end, however, so consider him in the middle of the first round of your rookie draft. The Jameis Winston-Howard connection will be strong for a long time. As for Brate, he had TE1 appeal entering Thursday night, but this derails his value and upside. He's now more of a fringe TE2. Your gut reaction might be to assume they'll go with a ton more two-tight-end sets, but the Eagles led the league in two-tight-end sets in 2016 with just 38 percent of their pass plays. It's simply not a package teams use much when passing.

Rookie-season projection: 38 receptions, 437 yards, 4 TDs

No. 23: TE Evan Engram to New York Giants

The Giants have had a void at tight end since Martellus Bennett left town for Chicago in 2013. A positional overhaul has left them H-back Rhett Ellison and intriguing rookie Engram. Unlike O.J. Howard, Engram is not a Y/in-line tight end. He will spend most of his time running routes and catching the football. Engram had a terrific combine, pacing the position with a 4.42 40-yard dash. The Ole Miss product is undersized (6-foot-3, 234 pounds) and thus needs work as a blocker, which could cost him snaps early on, but he's still positioned well for a big rookie-season role on passing downs. It's hard to get too excited for rookie tight ends, but if the Giants' offense bounces back after a down 2016 season, Engram could flirt with TE1 value down the stretch.

Rookie-season projection: 47 receptions, 509 yards, 4 TDs

No. 29: TE David Njoku to Cleveland Browns

Cleveland entered the evening in good shape with two first-round picks but ended up selecting three players on the first night of this year's draft. The first two picks were on defense, but the third is a potential star receiving tight end in Njoku. The Miami product is extremely young (20) and raw, but he is 6-foot-4, 246 pounds with long arms and freakish athleticism. He averaged 11.2 yards after the catch last season. Njoku has work to do as a blocker but figures to open his career as a receiving specialist behind veteran Gary Barnidge. Njoku is unlikely to provide much fantasy value as a rookie, but he is a TE1 in dynasty leagues. He has superstar upside.

Rookie-season projection: 34 receptions, 327 yards, 2 TDs
