This is kind of my theory on the upcoming draft, too. I think we will get the "backside" of a run of a position.
If there is a value guy at 21, TT will take him. If the S's go on a run, we get a WR. The WR's go off the board, we get a shot at a decent safety. It looks like the QB's might run also. If there is a good QB at 21, Thompson may pull the trigger on that guy.
