I'm starting to think about Darryl Drake too. Hester really has made massive strides as a receiver, Bennett looks a lot better and than there is Knox.
None of these guys have the skill-set of a #1, but if we can find a #1 and surround him with these guys we are talking about a WR corps that could be the best in the league in a few years (easier said than done though as #1 Wr's don't grow on trees and the Bears clearly have other issues which are far greater than the WR one).
