Alright I've played both and motocross is harder. It is so much stress on your body and physically demanding. People saying football takes more mental strength then motocross but how do you figure. In football you have plays and the conditions won't change. Motocross there are no plays and track conditions change every moto not to mention it takes years to learn what to do in each situation you will get into during each moto. Lets see a football player throw a whip and bring it back that takes some thought. Also there is much more of a risk every race can be your last. I broke my shoulder in a race once and got up and kept racing did tend to my broken shoulder and torn labrum until my moto was over let's see a football player do that.
