I’ll add that you really need 3 RBs a class to be a top tier offense. One who specializes in running down the right side of the field, and one who is elite at running on the left. Not just good elite, elite elite. Finally you need one guy who runs nothing but up the middle, much like Nick Saban has. In a perfect world you would also have a 4th: a “tricky back” who can run counters and catch passes, which are more complicated.
Do you think the one who runs to the left can be moved to striker? I think he's a striker in the staff's opinion.
