"People always ask me if I'm jealous of my brothers," Cooper says. "My family will tell you that I'm not jealous at all and that I'm their biggest cheerleader. But the truth is, I am jealous of Peyton and Eli—jealous that they get to play football every week. I'm jealous that football's their job, and they get to practice and work out and play games and sweat hard and run and hit and get hit. I'm jealous of all that, sure. But I'm not...I was never jealous, I should say, in a mean-spirited sort of way. I'm their big brother, and I love them. No, if I'm jealous, it's jealous of all the fun they get to keep having. That's one thing about me: I always did like to have fun."
