Work to do: TE Greg Olsen sliding to No. 31 overall was great fortune for the Bears. Desmond Clark is a serviceable starter with better blocking skills, but Olsen should provide an element of speed down the middle that QB Rex Grossman has never had at the pro level.

Instead of addressing needs at defensive tackle or wide receiver, Chicago reached for DE Dan Bazuin and RB Garrett Wolfe with its next two picks (Nos. 62 and 93).
