You are probably right about other coaches treating it differently. But knowing how things go down in Lawrence they would "T'd" up the ISU coach for throwing a tantrum during the KU's offensive "possession".....and that would have been 2 free throws and the ball for KU.
I just remember going nuts when it happened as I was screaming at the TV it was a 2 shot foul before they ever realized what happened. If that play happened at Hilton I guarantee you the court would have been littered with anything fans could throw and the refs would need an escort out of town.
