He helped out Marino's charity and spoke to Marino quite a bit. At the end of some of his charity events, they'd have this large party with former and current NFL players and celebrities. He said that Payton Manning was there for 1 event, it was years ago where I believe Manning was in his first year or 2 in the league, and the whole time was trying to get women up to his room. Manning was relentlessly trying to get my friends wife to come with him, it was to the point that my friend had to step in, as did Marino, to tell Paton to knock it off... He wouldn't leave her alone the whole night.
So yeah... He isn't the squeaky clean guy
