I don't think he did anything wrong and I think he'll do great at UNI (and I'm glad we don't have to play him).
Who knows if Bowen grew up an Iowa State fan? Lord knows that all of our previous coaches did not do a good job keeping former players invested. I do think that if I was in high school and had grown up a die hard fan of any school, I would strongly consider walking on to that school rather than going to another one. But not everyone would make that decision.
It would be nice, though, if there were more players that grew up wanting to be Cyclones. Allen Lazard was one that picked Iowa State because he grew up loving Iowa State.
