Everyone knows Jon Gruden is a "football guy."
From 2002 to 2009 he served as the head coach of the Tampa Bay Buccaneers and led the franchise to its first Super Bowl title.
But apparently, Gruden could be a little...obsessive.
During an appearance on Pro Football Talk Live, former Buccaneers quarterback Chris Sims talked about his former coach when the two were both in Tampa.
During the offseason, the former Texas Longhorns signal caller had planned to take two weeks off for his honeymoon. But, according to Simms, he had to come back two days early because Gruden wouldn't stop calling him.
After spending the past nine seasons as a commentator for ESPN's 'Monday Night Football,' Gruden announced he would return to the sidelines as the head coach of the Oakland Raiders.
He previously served in that position from 1998 until early 2002.
