Run defense still a problem

I haven't watched him play yet this year, but the next Kentucky game I can catch, I will be watching him. I have been reading a lot of reports about him and I've liked everything I've read about him. His only weaknesses are his conditioning and his technique, he gets too high with his pad level. that can all get fixed with coaching. Deone Walker- NT, 6'6"/345#. He could be a day one starter.
Oddly enough the things I’ve heard about him is his ridiculous conditioning and high motor and snap count. Perhaps I’m thinking of a different NT
