Hindsight and all that because no one was ever going to pick Mack over Clowney.
Clowney was supposed to be the next coming. Might still be!
They did actually talk up Mack in the pre-draft process. A lot of that was trying to drum up interest for trading down, but I am sure they considered it. Both Clowney and Robinson were the classic "physical freak" picks.
I have much more faith in Robinson working out than Clowney, simply b/c no one doubts Robinson's desire. He just has a long way to go as far as learning the game
