No, not really. Adam Robinson wasn't overly athletic he just understood where the cutback lanes were and could get chunk yardage. Before he went off the rails he consistently got Iowa into 2nd and 5(s) and 3rd and 4(s). He was a much better fit than Coker/weisman/Bullock ever were.
Zone blocking scheme was designed to plug any RB into it and to pick up chunk yardage even against 8 man fronts. It is clearly not the case. At this point i do not think even Shannonhan/Gibb could tweak it to make it work. It is outdated the way Iowa runs it. The problem is the o-line, the overall offensive philosophy is built around an outdated concept.
We we're 10th and 9th in rushing (Big Ten wise) when Adam Robinson played. I wouldn't call that successful although I agree he was a better fit for zone blocking. Again the only success we've had scoring wise was 2001, 2002 and 2008 and those were all years we had very rare skill players, and any scheme probably would have worked.
