The pro style guys hand off because they have to.. If the DT guy isn't having luck running, he can hand it off to the same RBs that the pro style guys would. It's about having options.. Like how everyone was going nuts when worley wouldn't keep any of those reads because his side of the field was wide open.. Options.
Incomplete passes are negative plays and you get a higher percentage with an athlete at QB. I would love to be a defensive coordinator with a DT QB on 3rd and 10. I know what he is going to do. It is just a matter of time.
Condrege Holloway was one of the greatest DT QB's I ever watch play the game. He had an All-American receiver in Larry Seivers and an All-Pro receiver in Stanley Morgan and never won an SEC tittle.
