I have my gripes about CamStache just like you, but I don't know if the answer is a Freshman. Frankly, I don't know that we have a better DE on the team. Watch the other guys when they're in - they all have glaring issues. Ankrah, EMart, Joe Carter... they all miss tackles, blow assignments, etc. Cam is slow but he's solid. I wish we had someone better, but we don't.
And Baker Steinkuhler has played quite well this year. He's been a non-factor most of his career, but this year he's been a man possessed. Watch the second half of Wisconsin if you don't believe me. He was unstoppable.
And this logical fallacy that "You don't know the Freshmen aren't better... so they are" is fun and all, but it doesn't mean anything.
Watching the Wiscy game with my in-laws. Father-in-law makes a comment about about Steinkuhler not making a lot of plays. We both enjoy plenty of good laughs as he makes about every-other play the rest of the game.
