Nah. Rivalry or not, flipping off fans and immediately running to get in the faces of the students - not a good look for a program.
Wave goodbye as you run off the court. Blow kisses. I don't care about that. Just stay above the line. Don't become trashy thugs. KSUcks has never had a team I can say I respect as a rival, at least not since the Jim Christian days (Chris Singletary, Ham & Cheese, etc.). OU has, Miami has, Buffalo has. Can't has never. That University borderline prides itself on being classless. There is zero respect for that team, that program, and that school.
Shut them up in Cleveland.
