I don't see many mocks (especially right now) predicting trades, so you will definitely be disappointed with that. I do agree with you that the value just isn't there for #3, but there has to be somebody willing to trade up in order for da Bears to trade back. I'd be down with Malik Hooker, but his injuries do worry me a bit. I first thought that the surgery was for a sports hernia, but I just learned that he had one for a torn labrum as well. He should recover, but I'm definitely worried.
I think that the Bills are most likely to trade up, though I wouldn't be surprised if they or any other team leapfrogs Chicago, since the Jags (#4) haven't made it known that they're looking for a new QB, nor will the Titans (#5). I hate this draft so far. With any of the last 3 drafts, I knew that a guy would fall to #3 that will be an exceptional player in the league. This year, I'm not so high on.
