A look at first Bills, Dolphins depth charts

Some depth charts aren't worth the paper they're printed on. As a season unfolds, injuries and position battles seldom are reflected accurately.

But I do think there is value to looking at the first roster breakdown of the preseason and the regular season.

With that in mind, I wanted to share the depth charts the Buffalo Bills and Miami Dolphins distributed to the media Monday. They open the season against each other Sunday in Ralph Wilson Stadium.

Most notable for Miami is that Jason Allen, generally viewed as a draft bust because he was selected 16th overall in 2006, has supplanted Sean Smith, last year's starter at right cornerback as a rookie.

Three rookies are in Miami's tentative 2010 opening-day lineup: right guard John Jerry, defensive end Jared Odrick and outside linebacker Koa Misi.

Newly acquired inside linebacker Bobby Carpenter is listed third behind Karlos Dansby and rookie Micah Johnson.

For the Bills, rookie C.J. Spiller is the first running back. Fred Jackson and Marshawn Lynch share the second slot with a slash between them and nobody listed third.

Bills coach Chan Gailey officially named Ryan Fitzpatrick the second-string quarterback and Brian Brohm third.

No other surprises on Buffalo's offense. Newly acquired tight end David Martin is second to Jonathan Stupar. Wide receiver Steve Johnson kept his status as the starter opposite Lee Evans. Roscoe Parrish and David Nelson are next in line.

Defensive end John McCargo, the 26th overall draft choice in 2006, is third on the left side behind Marcus Stroud and rookie Alex Carrington, a third-round pick.

Drayton Florence is ahead of Leodis McKelvin at right cornerback.
