It's entirely for show. He is a terrible person. Say what you want about organized religion, that is a whole other story, but those that deem themselves good christians don't maliciously corner women into restrooms. This is a quote from the article:
"Now more than ever, it's cool to be a Christian, especially professional athletes," Roethlisberger said. "One of the things I want to tell guys and tell people out there, I can be a really good athlete and a Christian. It's not one or the other. I can do both. I want it to be known to all of the young men out there, it's cool to be Christian and be an athlete. Go ahead and be the best athlete you can be and see if you can be a better Christian. And that's what I'm trying to do now. I'm trying to be a better Christian than I am athlete and football player. I push myself every day to do that, and it starts here. It's not always easy."
He is basically admitting to using christianity as a platform and ESPiN putting out articles like this is part of the problem. If he had just been your run of the mill NFL player, he wouldn't have been given chance after chance.
He can take his "i've found myself through christianity" manipulation and fuck right off.
