I'd go after Dockett, he's the mean 3 Tech we've been needing. Depends on how old he is, isn't he about 30 ? He's still good, but not the player he once was.
Kolb was playing well for the Cards, but he's not durable enough to last behind that OL. Similar to Hasselbeck last year behind our OL. Jackson barely survived it, Hass would've been murdered.
The other thing....why trade Flynn to the Cards ? He'd actually make them better. Flynn came in after sitting on the bench and getting limited snaps all season, and goes 5 for 7 and looked sharp in the face of the AZ blitz. Lots of folks said Flynn couldn't beat a blitz well, and he's not mobile at all. He rolled out, beat a Card defender one on one, broke the tackle, and completed a pass. I still think Matt is a starting caliber QB in the NFL, and I don't want that going to a team in division. Hell, I wouldn't want to trade him in conference.
