They're moving over to the 4-3, so a premier pass rushing DE is a must. It's something they didn't have as they transitioned this off-season. Now, they appear to have one, although he is going to have to prove himself at the next level. If I am Casserly, I would have tried to trade down with the Jets, allowing NY to take Bush (the guy I truly feel they want). Saints likely would have taken Williams, perhaps Brick. Either way, Tennessee is looking QB. At #4, you would have had the opportunity to take Brick or Williams. (And I would have taken D'Brick in Houston).
