Oh I think everyone agrees the call sucked for Iowa.....but most everyone, not a squawk fan, agree it was the absolute correct call, and not even that controversial.
I have seen this called many times, there are clips all over of it being called. I think a lot of the issue is, most of the time when someone waves people off the ball, they dont then field it and try to advance it. Most of those calls I have seen dont end in a score, so dont appear as big or important, but still the call is made.
If a returner waves off players, and never touches the ball, this call is not made, so most of the time that is the case, and what people appear to remember. Its just that he waved and then attempted to return, this I have seen called several times.
I seem to remember this call in an ISU game in recent memory too, just dont know when exactly.
