I would be shocked if he could DD. The guy was a 7th round pick and played like crazy to get to that starter role. Now he's kinda being thrown out by the emerge of Jennings and he still plays with a smile on his face.
I think you need a couple of guys like that. He gets the work ethic up, going out there as not the most physically gifted guy, but as a hard worker and running all over defenders. I love him.
