Thanks to a reader, Zach in Portland, we have yet another investigation into the University of Oregon cheerleading unit. "I've looked at hundreds of photos of UO cheerleaders out in the wild and a bunch have belly button piercings. In the photos you show they don't have them. Whats up," Zach wrote in an email. Great question, Zach. Good to see our readers nosing around the NCAA for more than just violations. Our research - JUMP!
