I actually think Jon's taking the highroad on this one. The easy "pussy" option for him would be to say fuck it and do big air.  For him to stand up to the event organizers, the haters, and his friends and say "hey, I'm not going to risk jeopardizing my career" is a hard thing to do. Just because x-games markets the sport as X-TREAM doesn't make the competitors dare-devils by any means. These guys are professional athletes, and as much as you might not like it they're business men in a sense. When they're marketing themselves, being in casts for a year isn't doing any good for business, or our sport for that matter.
