I seem to remember people did/do hate Iowa. Some of it, from way back when, was that many of the Iowa wrestlers (the Brands brothers included) seemed to embrace the "heel" role. That, and the many favorable calls, mostly stalling, back in the Gable era. Today, the Iowa guys generally seem like pretty good guys/sports. Not sure where the hate comes from today. Right now Penn State is every bit as dominate as the Hawks were during the 80's and 90's, but very few, maybe one, have taken a "heel" turn (to use pro wrestling terminology).
