Bills camp roster breakdown

PITTSFORD, N.Y. -- The Buffalo Bills are set to begin training camp Sunday evening, with 88 players counting against the 90-man offseason roster limit. (That figure includes safety Jairus Byrd, who has yet to sign his franchise tender or report to training camp.)

Here's a position-by-position breakdown of the current squad:

QUARTERBACK (3): Kevin Kolb, EJ Manuel, Jeff Tuel

Quick hit: It's an open competition, and all eyes on are Manuel, the 16th overall pick in April's draft.

RUNNING BACK (6): C.J. Spiller, Fred Jackson, Tashard Choice, Zach Brown, Kendall Gaskins, Drew Smith

Quick hit: Spiller is arguably the best running back in the AFC East, and pairing him with a healthy Fred Jackson will take pressure off whomever plays quarterback.

FULLBACK (1): Frank Summers

Quick hit: At 5-foot-9, 248 pounds, Summers will give the Bills a lead blocker to use in camp, but he still faces an uphill battle for a spot on the 53-man roster.

TIGHT END (5): Scott Chandler, Lee Smith, Mike Caussin, Chris Gragg, Dorin Dickerson

Quick hit: Chandler's health coming off an ACL injury is something to monitor, as the Bills don't have a proven receiving threat behind him. Gragg is a name to watch, however.

WIDE RECEIVER (11): Steve Johnson, T.J. Graham, Robert Woods, Marquise Goodwin, Brad Smith, Da'Rick Rogers, Marcus Easley, Chris Hogan, Kevin Elliott, Brandon Kaufman, DeMarco Sampson

Quick hit: The big question is who emerges as the starter across from Johnson. There's plenty of youth here, but little certainty.

OFFENSIVE LINE (17): Eric Wood, Kraig Urbik, Cordy Glenn, Chris Hairston (Active/PUP), Colin Brown, Doug Legursky, Erik Pears, Sam Young, David Snow, Thomas Welch, Antoine Caldwell, Tony Hills, Keith Williams, Zebrie Sanders, Zack Chibane, Hutch Eckerson, Ryan Turnley.

Quick hit: There's plenty of depth-level players here with positional versatility, but the Bills need someone to step up and lock down the left guard spot.

DEFENSIVE LINE (11): Mario Williams, Kyle Williams, Marcell Dareus, Alex Carrington, Alan Branch, Jay Ross, Jarron Gilbert, Torell Troup, Corbin Bryant, Izaan Cross, Aaron Tipoti

Quick hit: If healthy, there are two Pro Bowl players to anchor the line (Williams and Williams), but the third spot is up for grabs, and could come down to Dareus and Carrington.

OUTSIDE LINEBACKER (6): Manny Lawson, Jerry Hughes, Marcus Dowtin, Jamie Blatnick, Kourtnei Brown, Keith Pough

Quick hit: This could be a problem area, especially if Hughes isn't able to take the next step, given a fresh start in Buffalo.

INSIDE LINEBACKER (6): Nigel Bradham, Kiko Alonso, Bryan Scott, Arthur Moats, Chris White, Brian Smith

Quick hit: Mike Pettine's defenses in New York had David Harris and Bart Scott in this role. Bradham and Alonso are young, but will need to settle in to the new scheme quickly and anchor the middle of the field.

CORNERBACK (9): Stephon Gilmore, Leodis McKelvin, Justin Rogers, Ron Brooks, Crezdon Butler, T.J. Heath, Nickell Robey, Jumal Rolle, Kip Edwards

Quick hit: The AFC East is relatively weak at receiver, taking some pressure off the Bills to find consistency opposite Gilmore. Like most of the roster, there's plenty of youth here, but a need for players to step up.

SAFETY (8): Jairus Byrd (franchise), Da'Norris Searcy, Aaron Williams, Duke Williams, Jonathan Meeks, Mana Silva, Dominique Ellis, Jordan Dangerfield

Quick hit: It would be a surprise if Byrd doesn't return by the start of the regular season, but until then, the Bills will have to sort through a pile of young players for insurance.

KICKER (2): Rian Lindell, Dustin Hopkins

Quick hit: The Bills invested a draft pick in Hopkins, which gives him the edge in what could be Lindell's final training camp with Buffalo.

PUNTER (2): Shawn Powell, Brian Stahovich

Quick hit: Powell is the incumbent, but Stahovich could give him a run for his job.

LONG SNAPPER (1): Garrison Sanborn

Quick hit: No competition for Sanborn, who enters his fifth season with the Bills.
