Tough to say. There's a handful of CB's for the taking in the second round. I think the Browns will scoop one up with one of their 2 picks early.
Alexander, Davis(if he slips..hoping my Jets grab him to play opposite Claiborne), Oliver, Hughes(a bit small) and Toliver are all viable backs.
If the Bears are dead set on going CB...there is quality waiting at that second round pick. : )
