How about some of Duke's own fullbacks? Mike Curtis knew how to move the pile and supported excellent halfbacks such as Mark Leggett, Billy Futrell and Jay Wilkinson. In the same sense Curtis was a FB, really a power back, Steve Jones and Randy Cuthbert were also power backs, whether they lined up as tailbacks or fullbacks.
This is just a sample of really good power runners that have worn the uniform.
I am certain that if Cutcliffe had that kind of talent available, he'd find a way to use it. Those guys made their own holes and a single setback formation would have worked just fine for them.
