We've had what, 2-3 previous Nix drafts? Not much of a sample size from which to surmise what a "typical Nix move" is.
Also, every selection is a product of unique circumstances, both in terms of the status of your roster, that of your competitors, as well as who takes which players just ahead of you. Example: clearly the Bills liked Minter out of LSU (they invited him to Orchard Park for a predraft visit), but Arizona picked him just head of Buffalo's pick. So does the Alonzo pick suddenly become a "Whaley pick" or was the Alonzo pick born out of necessity since Arizona grabbed the guy we liked at the last minute?
Reading a changing of the guard into 3 picks is really oversimplifying the situation, in my opinion.
