I hated the #11 pick period. I didn't love any player at #11 for all of the above reasons and more. A lot of scouts were saying Oher had some learning disabilities and that he was a right tackle that maybe someday would make it to left tackle.
Even though we needed help rushing the passer rush I think a "specialist" could be had later; Sidbury, Everett Brown, Ayers. I saw Clint Sintim playing for the Giants the other night and looked good.
With that being said, with all the money currently tied up at DE I think I would have permanently fixed the LB position at #11 and taken just about any of the OLB's on the board to replace Ellison. That way you would be getting a starter and not a "specialist".
