This is the second part of an eight-part series in which Football Outsiders looks at the biggest holes remaining on each team after the NFL draft. Usually, that means the biggest holes remaining after the draft and free agency, but obviously 2011 is a little different. So some of these holes may not actually be holes if teams re-sign their own players, and other holes will be filled during free agency and won't necessarily last into training camp.
Buffalo Bills: Outside linebacker, quarterback
Part of the pain of missing on a first-round draft choice is that teams generally don't think about a Plan B. The Bills drafted Aaron Maybin 11th overall in 2009 with the idea that he would develop into a premiere edge rusher -- and they haven't drafted a pass-rusher since. Unfortunately, Maybin has been a nonentity, and three years later the only alternatives on the roster are Shawne Merriman and Chris Kelsay, two big names who are only a shadow of their former selves. Most observers expected Buffalo to take Texas A&M's Von Miller with the third pick overall, but the Denver Broncos threw a monkey wrench in that plan when they unexpectedly nabbed the Aggies pass-rusher.
