"I think to myself, do you know how many guys play their whole careers and never get the chance to be a champion? Yet, I was lucky enough to experience it.
Sometimes I stop and think, man that was big deal, a Super Bowl! And I had the opportunity to be a part of it!"

"It was so quiet on the bus. Everybody was just thinking about what they had accomplished. I was in a two-year stretch where things weren’t going very well for me-- my marriage was about over, I had some health problems, things like that. But this game was an escape, a chance to get away from everything for a while... So we’re on the bus, and Rickey Jackson’s son fell asleep on me... I was quietly looking out the window at all the buildings going by, and I thought, Wow, I just won a Super Bowl -- and here I've got this kid asleep on my leg"
