"Show me a good loser and I'll show you a loser," he said today as players cleaned out their lockers.
"I've got no more tears to cry," Newton said according to ESPN. "I've obviously had a lot of time to think about it. I've seen so much blown out of proportion."
A Broncos player could be heard boasting about his team's win as Newton was answering questions from reporters.
For his part, Chris Harris Jr., the Broncos player in question, said that he did not intentionally try to interrupt Newton.
"I would have been mad, too, if I was Cam," Harris told ESPN on Monday. "To be able to hear your opponent right behind you talking, nobody wants to hear that. So I think that was a bad setup, but things happen. But you have to deal with it and approach things like a man, and we've been in that situation where we lost a Super Bowl and be able to take things as they come. I'm just happy we were on the good side of things this time."
Newton said "that's cool" if he offended anyone by walking out, but he won't change his personality.
"At the end of the day, when you invest so much time and sacrifice so much and things don't go as planned, the emotions take over. That's what happens. As far as trying to be like this person, trying to be like that person ... the truth of the matter is I'm not trying to be like this person," Newton said today, according to ESPN.
He continued: "This is a great league with or without me. I am my own person. I said it since day one. I am who I am. I know what I'm capable of and I know where I'm going. I don't have to conform to anybody else's wants for me to do. I'm not that guy."
