According to USA Today's John Saracena' s tweet, Bill O'Brien is close to becoming the head coach at PSU. Yes, Bill O'Brien - he of the sideline shouting match with Tom Brady.
A person with knowledge of the Penn State hiring tells USA TODAY that only contract details need to be finalized before O'Brien is the man.
According to Bill O'Brien's wikipedia page, he spent 1993-2006 in the college ranks, as an assistant coach, mostly in the ACC. It doesn't appear he's ever been a head coach at any level.
This should be welcome news. O'Brien can join the growing list of Belichick assistants to fail (Crennel, Weiss, Mangini, McDaniel).
