Good grief... He was just talkin' a little smack. It's not as if he dislikes Manning... He's just being competitive - he wants to be remembered as the best QB when people think back on this period of NFL football. I appreciate the two of them, as one's legacy isn't quite the same without the other. I think they both realize this too, and appreciate each other (Manning, fairly recently, called Brady his friend and said regardless of what comes of deflategate, he'll remain his friend).
If the stories are true, the both hung out at a party at the Playboy Mansion. I am sure they both get around. I know a guy that says he fucked Manning's wife and they basically have an open relationship except for public appearances. I wouldn't doubt it. Peyton and Brady both play that " awwe shucks, I am just glad to be here" when you know they are banging girls left and right. Haha
