Will Guenther complain to the Big 10 Office?

In 2004, iowa came to Champaign. Pierre Pierce had just come off a suspension for misbehavior. Coach Guenther warned Orange Krush that they could not harass Pierce for fear of running afoul of the newly-implemented "sportsmanship rule" that Steve Alford of iowa instituted to protect Pierce. After iowa lost, Alford filed a complaint anyhow, even though Orange Krush didn't do anything to Pierce other than boo him.

Today, iowa fans gave it to Illinois, shouting "I-L-L-D-U-I" whenever Illinois was at the free throw line. What will Guenther do? Complain or just sulk about it?
