Not sure what to think of Michigan State. Elijah Collins I was higher on during recruiting than a lot of fans were, and I think he was better than his ypc suggested. MSU's OL was abysmal last year in run blocking. They finally starting rotating in some of the younger guys late, and their honestly was a noticeable uptick. But there is zero proven depth, so I think that's fair.
I think PSU has to be #1.
I might put Michigan #2. I'm not big on any of those guys. I don't think I'd put any of them in my top 6-7 backs. But I think all three might be in my top 12-15, and they provide different things. I always prefer that kind of backfield.
OSU #3.
