Sidney Rice in a Bears uniform is every Bears fan's wet dream. Seriously. It is.
On a more serious note, currently on their roster, the Bears don't have a wide out ready to play over 6'0". It's munchkin land in Chicago.
Sidney Rice, when healthy, is the prototype for a deep threat wide receiver. Last season, with no deep threat over 6'0" who can out jump a corner back, Cutler still was able to lead the Bears to the NFC Championship game. Imagine what he can do with a receiver who lines up in the right spot.
The Bears biggest, gaping hole, in my opinion, is wide receiver. Cutler has been pretty good even though he has no one to throw to.
If the Bears get a receiver, watch out.
