"Workouts are a small piece of the puzzle," said Nix, a former Auburn coach. "We go by how they play. Throwing's good. You can tell something about his release and you can tell something about his arm, but the only way you can tell if a guy can play quarterback is when he's being rushed and you've got coverage and you've got to throw it in a tight spot. That's kind of what we go by, 80 percent probably."
