Of those 7 round mock drafts, I like the one from the NFL the best. It has the most QB's going in the top of the draft, and I think one more goes for a total of 6 in the first 12 picks, though I think that DEN leapfrogs MIN and gets Mix, while the Vikings, afraid of losing Jefferson, take Penix, Jr. I like the idea of the Colts moving ahead of the JETS at #9 and taking Bowers, making it likely for the JETS to swap picks with the Broncos and surprising the Vikings, who didn't see the JETS not getting Bowers. Of course, it's also possible for the Broncos to trade with the #9 Bears to take Nix, but the Colts have a 2nd this year to offer the Bears and the Broncos don't.
Bottom line is that the Vikings don't get Nix.
