Two problems with your post (aside from the cartoonish, outlandish, wholly unnecessary misogyny throughout).
1.) The idea that teams didn't scheme for AD because he was coming off of an injury is laughable. No, you're right, they were so intimidated by Christian Ponder that they trotted out 7 DB's every play...
2.) The Lions didn't have the worst run defense in football last year. They were ranked 16th, exactly average. You could argue they underperformed, even.
I'm not saying he'll crack 2k again, but he'll be a force assuming he's healthy.
