Pittsburgh Steelers quarterback
said he got caught up in being a caricature called Big Ben, not the grounded player and person he once was, leading to his off-field problems - and affecting his play.
In his first detailed interviews since a Georgia college student accused him of sexually assaulting her in a nightclub bathroom on March 5, Roethlisberger told Pittsburgh TV stations KDKA and WTAE that he expects to be booed this season.
He also apologized extensively for his actions, and promised to become the role model he should have been throughout his career.
"I got caught up being Big Ben the whole time. I lost track of who Ben Roethlisberger was. It's not something I'm proud of," he told WTAE. "I've made mistakes, I know I have."
He said he wanted to apologize to fans for "being immature, for being dumb, for being young, for not knowing any better."
