I understand the seriousness of concussions.

Some guys lose their focus. They get caught up in the business deals or the endorsements, and they lose their focus. For me, it's always about football. I've never lost sight of what's making all these other things happen.

Nobody really wants to hear about anybody else's injuries. Or how your back feels. Whose back doesn't hurt?

I feel one of the most significant honors a player can have in his sport is to have his number retired. Certainly for me to have that at Tennessee, it's with great pride.

Certainly our job as an offense to try to score points and that's running the ball, throwing the ball, whatever it is. Somehow, someway we've got to try to score points to help our team win. That's where the focus is and it's pretty easy just to focus on that.

When you get a lot of money thrown at you, you can make some dumb decisions without the right advice.

I think I could describe the perfect quarterback. Take a little piece of everybody. Take John Elway's arm, Dan Marino's release, maybe Troy Aikman's drop-back, Brett Favre's scrambling ability, Joe Montana's two-minute poise and, naturally, my speed.
