New England Patriots: Cornerback
Receiver looked like a sure bet for this title a month ago, but the Patriots have weeded out Chad Ochocinco and Anthony Gonzalez. Now, the best position battle is likely cornerback, where New England has an interesting mix of young players. Devin McCourty, Ras-I Dowling, Kyle Arrington, Sterling Moore and Alfonzo Dennard give the Patriots five capable players.
New York Jets: Offensive tackle
Both sides need better play than the Jets received last season, but are there players in place to fix the problem? Wayne Hunter shouldn't be starting in the NFL, but is there a better option? The left side is also worth watching.
Buffalo Bills: Cornerback
After taking cornerbacks Stephon Gilmore and Ron Brooks in the 2012 draft, Buffalo now has a log-jam at the position. Aaron Williams was a second-rounder last year, and he's joined on the depth chart by Leodis McKelvin, Terrence McGee and Justin Rogers. One of the big names will likely have to go.
