The best Iowa offense I've seen in my lifetime was when Iowa had their most athletic quarterback during that period: Brad Banks. Granted that was the best team for a lot of other reasons, and he was heisman candidate caliber. But with that said, I would like to see Iowa with a pass first-athletic quarterback that challenges defense with his ability to run. How many really good BCS teams this year (really good offenses) had an immobile quarterback? I can't think of very many. Not to say that Vandenberg and Stanzi (for example) are poor athletes because they are not. But they are not runners that can consistently pick up yardage on the ground, when plays break down.
However, I still want to see Iowa run a pro-style set, which they probably will for some time into the future. I put serious value in the fact that Iowa is capable of producing loads of NFL caliber offensive lineman. Honestly, do I anticipate Mitch Keppy or Ryan Ward or Reid Selby making an NFL roster as an OLineman, yes I do. I also believe Iowa is capable of a NFL worthy TE every year too. Based upon this, my vision of ideal offense for Iowa is:
1) A big, dominant OLine with size across the board and depth. See Wisconsin (they stole our recipe)
2)Two different style RBs, both getting carries. A bigger back that runs downhill and a smaller back with a great first step that hits the hole really fast. (Shonn Greene and Jewel esqe)
3) A bruiser lead blocking FB that can catch passes in the swing game. His blocking allows offense to run between tackles, isolation blocks etc.
4) A go-to TE with NFL written all over him. He can catch passes over the middle, break tackles and be a physical presence attached. Also a second TE that can give a power-double tight look, physical run blocker. (Moeaki and Myers maybe)
5) Two complimentary WRs, Mcnutt and DJK come to mind. Both are capable of demanding a double, both can catch short, sideline routes, take the top off the D etc.
6) Last but not least, a QB with enough size to have a commanding physical presence and avoid injury. He is a good enough runner to pick up first downs with his feet, athletic enough to incorporate some option looks into the offense. He has the arm to make all different throws well enough. He is cool enough to lead the offense. The QB does not need to be John Elway, he just needs to be really solid, and the beneficiary of everyone else being really good (see 2002). As for a comparison here...I guess I could say Brad Banks. But who knows
Pretty much I am modeling the ideal after the 2002 offense. Starts up front with a great Oline and that translates to a very successful running game, and plenty of options to stretch the D emerging from the presence of the run.
