I think Crawford is a better 3-4 end than 4-3 end. He has problems using his hands to get off of blocks and prefers to use power.
Well, I honestly don't care how he gets to the passer, as long as he gets there. If he pancakes the OT, as he did with Parnell, and gets there - who cares? And he will learn more moves, he will get better. And he's far and away better than Mincey right now. Bigger, stronger, faster, quicker, works harder, more of a leader. He is Canadian though.
I could see Crawford turning into a Jim Jeffcoat type player. At the very least, Tony Tolbert. I think he's a perfect fit for SDE and a much better fit than Mincey at the WDE.
