ESPN's Robbi Pickeral says Bullock got angry when he heard an Ohio coach say that UNC couldn't win without Marshall:
North Carolina sophomore
Reggie Bullock was playing defense near Ohio’s bench with somewhere around 12 minutes left in regulation when he overheard a Bobcats assistant coach say it:
“They can’t win without Kendall Marshall.”
And boy, that made him mad.
“That just got to me, for someone to say that my team can’t fight, can’t win without our starting point guard,’’ said Bullock, usually one of the most mild-mannered members of the team. “That lit a fire under me.”
