Bruce Arians was Ben Roethlisberger's mentor in the early Big Ben years in Pittsburgh but it took a veteran linebacker to put him in his place. According to Arians new book...
“During the  season Ben often acted immature, as if all the stories that documented the greatness of ‘Big Ben’ had gone to his head,” Arians writes. “He wasn’t signing as many autographs for teammates as he should; some days he would sign, some days he wouldn’t.”
Late in the year, with playoff hopes dwindling, several veterans addressed the team. Linebacker Joey Porter, according to Arians, singled out Roethlisberger with “blunt language,” telling the quarterback that he “needed to be ‘one of us.'” Per Arians, Roethlisberger instantly “became a different person” and “grew up fast.”
I don't think there was any doubt that Ben might not have been the most stand up dude early on.
