I don't understand why Beau and Warren being gone affects RB3. I don't think RB3 will be on the field much. I see the departures of Beau and Warren as an opportuinty for Dinkins, RBs 1/2, and WRs. I suspect we'll see two back sets, Singleton in motion, and becoming a slot reciver as he has good hands and is a great open field runner. We also didn't run a lot of bubble screens last year.
My only real question is who is our changeup QB if any? I don't think our backups are any better runners than Allar. Do we have someone in the wildcat for short-yardage situations like Warren did last year? If so, who, Dinkins, Ripp, Reynolds? I wouldn't be shocked to see Tony Rojas playing some offense as it has been reported that he's running 4.4 40s at 235 lbs.
