Knowing the Buffalo Bills and the way they like versatility in their personnel, one can expect to see a lot of odd lineup combinations from them - particularly during training camp. Still, it's a bit jarring to see a 304-pound player standing up and playing outside linebacker. That's exactly what Bills fans saw at practice on Monday, according to WGR 550's Joe Buscaglia.

With starting strong-side linebacker Chris Kelsay sitting out the practice session, second-year defensive end Alex Carrington spent the day running positional drills with coach Bob Sanders and the outside linebackers. Then he took first-team reps with the defense at that position.

Buscaglia did note on Twitter that Danny Batten got some first-team reps at outside linebacker, as well, so it's not as if we should start listing Carrington as Kelsay's backup on the depth chart. That said, this is a very curious move. I have no words of wisdom nor insight on this oddity, except to offer this: it's clear that the team prefers a run defender to a pass rusher at this position, particularly in the base defense.
