Brady Quinn in Chicago would be interesting. With Charlie Weis having trouble at Notre Dame, maybe he could be coaxed out of South Bend to run the offense with Lovey running the defense. Even if Weis can turn it around this year at ND, he plays on Saturday, and could easily make the short drive (more likely chartered flight) to Chicago for a skybox view.
By no stretch of the imagination do I think Quinn is the only person the Bears should think about in the 4th position, but it would be very interesting. Calvin Johnson would be great, but I think they could save that pick and take Dwayne Jarrett at the end of the first round. One mock Draft had him going 40th, which is way too low for a kid as talented and exciting as Jarrett.
Briggs is an exceptional talent, so it would be a shame to see him get away without anything to show for it, so I have no doubt the Bears are lookin' to wheel and deal.
