PHOTO: Bill Belichick, Rex Ryan share a laugh at combine

Bill Belichick and Rex Ryan, two head coaches who have engaged in more than a few AFC East battles over the years and who should probably hate each other, showed up to the NFL scouting combine at the same time Friday and shared a laugh as they entered the building.

Belichick was decked out in a gray hoodie (what else is new?) that had his name emblazoned on the front (wait ... what?). 

Ryan wore a Super Bowl XXV-edition Thurman Thomas jersey. He sure knows how to win over the fans in Buffalo.
