Breaking down the Buffalo Bills initial 53-man roster, position by position:
Analysis: Continued turnover at this position. Orton will need to learn the Bills' system quickly. Bills management stressed the importance of Thad Lewis and Jeff Tuel having experience within the system when passing on adding a quarterback this offseason.
Analysis: This group has been set since Brown was acquired in May.
Fullbacks (1): Frank Summers
Analysis: Once Evan Rodriguez was released, this group was set.
Analysis: The Bills tried to deal T.J. Graham but couldn't find a suitor. He's eligible to return to the practice squad; it's unclear if either side has interest.
Analysis: This is the same group as last season. Smith's toe injury bears watching. The Bills may watch the waiver wire here.
Analysis: Ideally, the Bills would've liked Kouandjio to become their swing tackle, but his preseason struggles have him destined as a game-day inactive. Can the Bills find an upgrade to Hairston on the waiver wire?
Analysis: If Williams' back injury keeps him out of the opener, expect Richardson to start in his place. The Bills kept Urbik over Doug Legursky, a fellow veteran. He could replace Legursky as the top interior backup for games.
Analysis: The Bills ended up going an extra player deep here. Smith is the biggest surprise of the 53-man roster, although he played well in the preseason. There may not be much of a role for him during regular-season games, given the depth here.
Analysis: The Bills passed on keeping a fifth tackle and released Landon Cohen. In a pinch, Wynn could probably shift inside.
Analysis: Brown will likely step in for Bradham in the season opener. Johnson and Powell are special-teams contributors.
Analysis: As expected, the Bills went six deep here. Brooks should be active as a special-teams contributor, while the Bills started to experiment with Graham at safety late in the preseason.
Analysis: This is the same group as last season, minus a Pro Bowler in Jarius Byrd. There's still questions on how well Searcy (or Duke Williams) can fill the void.
Kickers (1): Dan Carpenter
Analysis: We'll count Carpenter as the only pure kicker on the roster, although punter Jordan Gay may be the kickoff specialist.
Punters (2): Colton Schmidt, Jordan Gay
Analysis: The Bills will need a replacement for Brian Moorman and Schmidt is the first batter up. Gay is another possibility, if he can handle both punts and kickoffs.
Long-snappers (1): Garrison Sanborn
Analysis: Sanborn, who just received a contract extension, is one of the game's best.
