I hate to say it but jones reach is just too long. Machida is going to have alot of trouble here. The style to beat jones reach is someone like Anderson who jones actually tries to copy. Anderson would slip inside the pocket and killshot jones with the very first jab, in round 1 
I know it's been said about other fighters (Machida for example) but I don't see anyone beating Jon Jones. I really believe he's just too damn good and well rounded to be defeated by any current UFC LHW.
Jones is going to kick the hell out of Machida's legs.
