i would agree with auburn on mcgrath but carmicheal was very beatable although he won championships vuillemen,reed and stewert all beat him straight up regulary
and if vuillemen and reed hadnt been injured in certain seasons they would of won the championship as opposed to ricky . all that said ricky was still defently one of the best but i just dont class him as greatest although outdoors is another story.any way in answer to the question mcgrath was the greatest of all time with an honerable mention to carmichael,stanton,hannah,johnson and ward

c dub you are the one who dosent have a clue the question is for supercross not motocross .
if it was who was the best dirtbike rider off all time it would be ricky but thats not the question so try reading the question properly next time

ok.. james v has no clue what he is talking about.... RC is for sure the best of all times.. no doubt... he has had more wins ever than anyone else.
