Well, according to Evan Silva and NBC's Pro Football Talk and their first edition of a 2012 Mock Draft both of them are first round picks, with Kalil going third overall to the Minnesota Vikings and Perry heading to the Windy City to join the Chicago Bears.
Silva notes that the Vikings most glaring area of need is at left tackle, and Kalil is seen by many as the best tackle in this draft class, meaning this could be a match made in heaven for them. With Andrew Luck and Robert Griffin III likely going No. 1 and 2, this is one of the more logical fits in this years draft.
As for Perry, some have felt he'd be a better fit elsewhere but Silva likes him going to Chicago, noting that he and defensive coordinator Rod Marinelli will be a good fit.
