I did this last season and it turned out pretty well for the Bucks. I think football still boils down to running the ball well and stopping the run well. Last year the Buckeyes had an excellent season with the Delta/difference between average yards per carry for and against. At season's end they finished with a +2.4 average gaining 5.0 yards per carry and giving up 2.6 yards per carry.
Attached is the discussion from last year if you care to take a look.
