I agree. And to answer the OP's question: Toren Young as a "conventional FB"? - absolutely not. Young as a "2nd RB"? - absolutely yes.
Two thoughts:
1) For whatever reason... if we're not going to use a "mobile" quarterback, how can we produce more of a consistent rushing threat? Can we feature two true running backs out of shotgun sets? Can we continue to get speedy receivers involved in lateral run players, like Tracy and Smith-Marsette? As for the mobile quarterback part, we've had three awesome years of Nate Stanley. IMO, he is a good athlete, but he lacks the quickness of a modern running quarterback. And we might be looking at another 2-3 years of Spencer Petras,who seems to be in a similar category of mobility as Stanley?
2) How effective is Iowa when featuring a true (old school) fullback? What is the opportunity cost of having a fullback out there? Deep down in my soul, I dream of Iowa running base I-formation offense with the classic run sets (Iso, power, trap, counter)... and attacking downfield with play action passes, TE seam/crossing routes, and deep posts / layered WR concepts. This foundation "Pro" offense is built around the fullback in many ways. Personally, I love seeing Iowa in the I formation. With ~100 roster spots, I think Iowa can and will afford to have 1-2 of these old school fullbacks on the roster at any given time. But if we're going to take the next step forward offensively, how much does that involve a one-dimensional fullback?
