Here's an excellent article on DeHaven's return to Buffalo. Here's the part that SCREAMED to me:
"Buddy Nix is a football guy, just wait and see," DeHaven said. "You don't have to take my word for it, but Buddy Nix knows football players. There are a lot of guys out there who know heights and weights and 40-yard times, but not all of those scouts can tell you whether the guy is a football player. Buddy Nix can."
