"People are probably going to be reluctant to say it, because it seems like he's been there forever, but he's still a young player," Manning said. "He has so much great football ahead of him. Look, he's extremely fun to watch, he plays with a joy out there, which I think is great. I think his teammates feed off of that. He's extremely competitive. I think it just says a lot about him that he doesn't say, 'Hey, I'm not going to try and get any better this year. I've done this. I'm going to relax this offseason and not work as hard.' It looks like he works even harder each offseason to be even better the next year."
