Any of the RB's with an open lane

The RB's will be fine. While they're not going to be as explosive as Dexter Williams was this year, with at least a reasonable running lane opened up, they'll do just fine.

Tony Jones Jr. can pound the ball up the middle, Jafar Armstrong can move with more speed, etc. Then there's Kyren Williams, who seems to have been an underrated player in high school.
