I've been watching mma for about seven years and I've helped coach (legitimately, before anyone says that I haven't. It's a little gym where I also learned to box.) anyway, everyone says they figured out how to beat Jones... But I've never seen anyone give the real key to victory. The answer is simple. It's body punches. Alexander Gustafsson may not have won, but he arguably did best against Jones (the only other person I'd say did well was Machida). He also landed 27 body shots and was constantly threatening. This, combined with his long reach and large stature, allowed him to take down Jones. JBJ tires easily (through damage) but he can take a lot of it. Gustafsson was more resiliant to damage, and though he isn't as skilled as Jones, his intangibles allow him to stay standing and keep fighting through pain. He's kind of like Goku in this way, if you think about it. He takes damage but his ability to fight doesn't fall like Jones' fighting ability did (in that fight). Anyway, the way to beat Jones is to fatigue him quickly, because when he gets tired, he's much easier to hit.
