Before you get to the actual physical part of the game, before you get to trying to avoid the 300-pounders, or completing passes against these guys that are fast, you have noise, which is an irritant.  You can’t hear. How many other people work where you just can’t hear? You have weather, 60 percent of the time. Sometimes you’re playing in a dome, it’s perfect weather, but weather’s a factor. You have time. That’s the big difference. Baseball players, there’s no time. There’s no clock. The guy can pitch whenever he wants. We have to operate under a clock, and then you have ten other guys that you’re trying to coordinate out there. So if you are not strong mentally, and sharp mentally, and rested, you will get behind in that aspect of the game.
