Benson's the top guy this year, but I think Wright is right on his heels.
I also really like Jonathan Brooks' all-around game. Good size, natural zone runner, great hands, and he was the best pass blocking RB in college football last year per PFF. The obvious question is how much juice is that ACL injury going to cost him. But on tape, he's the best RB in this class, and a no-doubt 3 down starter.
After those three, I just see committee backs at best. Corum might light it up if he makes it to a McVay tree offense. Irving has great tape, but marginal size-speed RBs usually don't do well in the pros. Allen is a fullback.
