Arthur Moats was a DE in college. Since he's been on the Bills, he's been shuffled all over the field and back again, from ILB to OLB to DE and back and forth numerous times. Moats is back at DE and is earning praise again from Gailey: "In recent weeks, he's moved back to his original position in the NFL -- DE, which is also where he played in college -- and he's given the Bills' injured defensive line a boost with limited reps. “We've been a little thin at defensive end and to give those guys a blow,” Gailey said. “And to be honest, the first time he went in there two weeks ago, he pushed the tackle right back into the quarterback and we remember what he did do when he was playing defensive end. It makes you remember those things, he's been at linebacker so long. So he's been a good change of pace to give us a little rest and give a little pressure to the quarterback.” http://www.cbssports.com/general/blog/nfl-rapidreports/21294920/bills-notebook-surgery-likely-for-rt-chris-hairston
Also, look at last year when Alex Carrington & Spencer Johnson were playing at OLB. Two 300+lb D-linemen playing OLB? WTF were they thinking. Carrington is having a break out year this year (so far) and had his best game to date this past Sunday. Aaron Williams is another player that draft experts said would be a safety in the NFL, but yet the Bills put him in at CB. AW has been terrible at CB for the Bills this year.
