I hope you are right, but …
Recall what Will's dad said about him in the off season. They were going to get his weight up so that he would keep in the 290 range for the entire season. The O is a wearing one, with everyone blocking (I mean really blocking, not just leaning on people) on every play, a lot of running, and play action for almost every pass. In the heat down here, the problem of progressive weight loss is a real one. And, as you point out, if you are down to just muscle, guess what begins to wear away? That is especially tiring as well.
Well, like I said, Benson has been training with pros off season (I think I read that) and you are probably right. I sure hope so.
