Here's a player-by-player look at the New York Jets' 53-man roster:
QUARTERBACK (3)
Ryan Fitzpatrick: Take his averages over the past five seasons, project them over 500 attempts and the results are 24 touchdowns, 17 interceptions -- probably not good enough to get the Jets into the playoffs.
Bryce Petty: Despite 101 snaps in the preseason, the rookie still has a lot to learn and he'd probably be used only to finish out a game in the event of an injury to Fitzpatrick.
Geno Smith: He won't automatically regain his starting job when he returns from a broken jaw, which should be in two to four weeks, but he'll apply pressure on Fitzpatrick.
RUNNING BACK (4)
Chris Ivory: In 2014, he averaged only 3.1 yards per carry with two wide receivers on the field, but 5.2 with three or four in the game -- and that bodes well in Chan Gailey's spread system.
Bilal Powell: Some teammates call him the most under-rated player on the team; he'll be the third-down back.
Zac Stacy: The St. Louis Rams castoff is a steady player who can do a little of everything, as he showed with 233 yards from scrimmage in the preseason.
Tommy Bohanon: The fullback doesn't have a prominent role in Gailey's offense, but he'll also play on special teams.
WIDE RECEIVER (6)
Brandon Marshall: He's the first player in Jets history with seven 1,000-yard receiving seasons to his name; not even the great Don Maynard had that.
Eric Decker: He's quite comfortable with being the No. 2 option in the passing game, and you might see him in the slot more than last season.
Quincy Enunwa: He went from the bubble to No. 3 receiver in training camp, a meteoric rise for someone with no career receptions.
Jeremy Kerley: He's not as versatile as the others, one of the reasons why his role will be reduced.
Devin Smith: Sidelined since the first day of camp with broken ribs, the Jets' second-round pick still has a chance to make an impact as a vertical threat -- but he's way behind.
Chris Owusu: Right now, his primary role will be to return kickoffs.
TIGHT END (2)
Jeff Cumberland: Because tight ends get only the scraps in Gailey's passing offense, Cumberland might be hard-pressed to equal last season's reception total (23).
Kellen Davis: Known for his blocking, not his receiving, Davis will be used mainly in two-tight end packages.
OFFENSIVE LINE (10)
D'Brickashaw Ferguson: At 31, he's no spring chicken, so he'll have to make adjustments to keep up with a steady diet of speed rushers.
James Carpenter: He feels more comfortable in the Jets' man-blocking scheme as opposed to the Seattle Seahawks' zone scheme, which he did from 2011-2014.
Nick Mangold: With an experienced signal-caller like Fitzpatrick behind him, Mangold can concentrate on his assignments and the line calls without having to worry about a young quarterback.
Willie Colon: He brings the nasty to the line -- sometimes a little too nasty, as he committed a team-high 14 penalties last season.
Breno Giacomini: He has to cut down on the penalties (eight) and be more consistent on a week-to-week basis.
Brian Winters: The former third-round pick is backing up at both guard spots.
Ben Ijalana: He's Brick insurance, playing behind one of the most durable players in the league -- which means he doesn't get to play.
Dakota Dozier: Coming off what amounted to a redshirt season (zero snaps), Dozier is the No. 4 guard, which means he might not be active on game day.
Brent Qvale: Another lineman with no NFL experience, he can play guard or tackle on the right side.
Jarvis Harrison: If he's on the field, the Jets are in trouble. This is a developmental year for the fifth-round pick.
DEFENSIVE LINE (7)
Muhammad Wilkerson: He should have the opportunity in Todd Bowles' one-gap scheme to put up big numbers in sacks and tackles for loss; plus, it's a contract year.
Damon Harrison: Big Snacks believes he's the best nose tackle in the league; he's definitely in the conversation. Also in a contract year.
Leonard Williams: With Sheldon Richardson serving a four-game suspension, the Jets' No. 1 pick will be in the spotlight, especially in the base defense.
Leger Douzable: He's a useful backup who can play in the nickel and contribute on special teams.
Stephen Bowen: The young pups on the line can learn a few things from the oldest guy in the room.
T.J. Barnes: He's 6-foot-7, 364 pounds. He doesn't just block the sun, he creates a solar eclipse.
Deon Simon: No one noticed, but the seventh-round pick actually had a solid preseason.
LINEBACKER (8)
David Harris: His role will be the same as it was in Rex Ryan's defense -- make the calls, get everyone lined up properly and play every down.
Demario Davis: He loves the idea of playing in a one-gap system, which should create more run-and-hit opportunities.
Quinton Coples: The former No. 1 pick isn't a fast starter; 9.5 of his 16.5 career sacks have come in the final four games of the season.
Calvin Pace: Now that Jason Babin is gone, Pace, 34, is the oldest player on the team.
Jamari Lattimore: The former Green Bay Packers starter will be a core special-teamer.
Lorenzo Mauldin: Once his sprained knee is healed and he learns his assignments, the third-round pick could crack the rotation as a situational pass-rusher.
Trevor Reilly: No one plays harder than Reilly, who should have a role on special teams.
Erin Henderson: Welcome back, Erin. The former Minnesota Vikings starter sat out last season as he battled a drinking problem.
SECONDARY (10)
Darrelle Revis: He's the key to the defense; his ability to shut down the opponents' No. 1 receiver will allow Bowles to operate his blitz-heavy scheme.
Antonio Cromartie: With Revis on the other side, Cromartie will be targeted a lot. Those preseason hiccups need to stay in the preseason.
Marcus Gilchrist: He can play safety and slot corner, offering the kind of versatility that will allow the Jets to stay in base personnel against certain spread formations.
Calvin Pryor: After a quiet rookie season and a quiet preseason, it's time for the former No. 1 pick to make some noise.
Buster Skrine: He's a significant upgrade in the slot over Kyle Wilson. In other news, Donald Trump likes to talk.
Jaiquawn Jarrett: Bowles likes to use defensive backs in his blitz packages; Jarrett could be one of those guys.
Darrin Walls: A year ago, he was an opening-day starter. Now he's the fourth corner.
Marcus Williams: Amid last year's debacle at cornerback, he got to play 446 snaps, an invaluable learning experience. And it shows.
Dexter McDougle: Finally healthy, this will be a learning year for the former third-round pick, who might not dress on game day.
Ronald Martin: The rookie safety was plucked off the waiver wire after being cut by the Seattle Seahawks.
SPECIALISTS (3)
Nick Folk: This is a big year for the usually reliable place-kicker, whose field goal accuracy dropped nearly 10 points last season.
Ryan Quigley: Relatively steady, if not spectacular.
Tanner Purdum: It's hard to believe, but this will be his sixth season as the long-snapper. He's doing something right.
