I think you'd have to start with Kyle Williams. He is the best player on the team, but:
1. If Troup develops this year, then he is a better fit for what we are doing on defense.
2. It's going to take a lot to get Luck.
If the team with the top pick needs a QB, then I think there's practically nothing you can do to get the pick. If not, then the odds are pretty good their chief weakness is on defense.
