The Bears signed a pair of one-year contracts with DJ Williams and James Anderson to play middle linebacker and strong-side, but they needed to add some younger players to the position at some point.
Bostic's a guy that I pegged as someone that could use that year to develop - at Florida, the intelligence and knowledge of defense was there, and he is a hard hitter that fills run lanes well, but lacks a little speed and quickness.
National Football Post marks him as having better quickness than I see, and he has a little ability to get after the passer, with solid tackling and good hands to keep blockers off him. But he doesn't have a lot of straight-line speed, and he can be driven out of plays.
SB Nation's site for all things Florida Gators, Alligator Army, cited Yahoo's Jason Cole that he could be taken ahead of Manti Te'o (which didn't happen), but cites his intelligence and skills giving him the ability to play either inside or out.
