Walton is most dangerous as a pass receiver and short yardage runner. He averaged under 4.0 YPC coming into today, when he averaged just 1.5 YPC on 13 attempts. That's a dreadful number for an RB in college regardless of experience.
The OL is the biggest reason for our running game's ineptitude, but we also don't have Miami speed in our backfield and it shows. Walton didn't play well enough, IMO, to carry the ball 120+ times this season.
A big reason why Ice Harris needs to go is to eliminate the possibility of favoritism towards his former HS RB. But Walton is a nice complimentary player who should contribute quite a bit these next few years and show improvement with better coaching.
