Greg Schiano, Ohio State's defensive coordinator and Bill Belichick friend, was hired and then fired from the head coach job at the University of Tennessee in the span of a few hours. There was a huge backlash that came from people involved with the university and the state because Schiano apparently knew about Jerry Sandusky raping kids at Penn State when he was a coach there and did nothing.
Here's what Belichick had to say about him:
"Greg Schiano had been an annual visitor to New England Patriots' minicamps prior to becoming the head coach of the Tampa Bay Buccaneers. Schiano has consulted with Belichick on a variety of topics, most notably defense."
