okay so ive read all of these and ive played football for 9 years and raced moto for 4 ive always thought motocross was easy cause id only go to the dunes but on a track people dont realize how hard is really is you do have to stay focused and control your breathing now im not saying moto isnt hard cause it took me forever to breathe get rid of arm pump all of that i thing there equally as physically challenging but talent wise i think football is alot more challening mentally than anything. also i would love a "pro" moto rider thats probly 5 11 160 lbs to go get hit by a middle line backer or lineman that is 6 5 280 its not fun... skill wise there pretty equal, i think it personally thought it was alot harder learning to play football compared to learning how to ride. so im gonna give football the upper hand on all around harder sport but physically demanding i think there pretty equal, one thing i will give moto over football i like that you cant blame anyone but yourself if you loose.
