Cam Newton says he was a bad teammate during his Rookie of the Year season, but his fellow Panthers say he just needs to trust them more. Newton says he had difficulty adjusting to losing during Carolina's 6-10 season. "I was very immature," Newton told Yahoo! of his reaction after losses. "I'll be the first one to tell you, the pouting and the moping, I kind of overdid it. I know that. I was a bad teammate. I shut off to some people who gave unbelievable effort. ... That's where I have to mature."
