aitken didnt die, thank god.
and pete, he died in a regular freestyle moto-x comp. the jump wasnt even huge like the sh!t they build in the X games. he just under rotated, is all. you cant really change the basic freestyle event of moto-x or put limits on it and be like "oh hey, no more flips." The majority of the fanbase will become disinterested, and stop following it.
As for the Xgames, they're fucking stupid now. the action sports community has pretty much stopped watching it completely, and primarily watch the Dew Tour now. the only people who watch the Xgames now are people who actually WANT To see someone do a triple flip or get fucked trying.
