I think the biggest problem other fighters have faced; Shogun, Rampage, Evans, Bader is that they concede to striking with him at range which is why they got picked apart. Chael's biggest advantage is going to be not getting hit by rangy shots because he almost never fights at range, that's not his style. Jones breaks down guys by pushing them back and peppering them with jabs, kicks and fancy moves and then once they are near done he closes the gap and demolishes people with elbows and knees.
It will be a lot harder for Jones to do that if he's getting pushed backwards and he can't get Sonnen's back to the cage, in some ways Sonnen has much better of a chance than any other guy he's faced (except for Evans who fought like a dumbass). A guy like Rampage stood nearly 0% chance against Jones because Jones' range is perfect for plodding power punchers or guys like Machida that like to stay on the perimeter, it's the perimeter fighting that lets Jones methodically dismantle fighters physically. When he's standing there kicking Belfort in the knee caps and Belfort doesn't do anything it's no wonder he wins all his fights. Don't stand in front of Jones, don't do it for 1 second would be my advice to every fighter. If you're standing there the fights already over. Speed, agility, strength, toughness all mean nothing with the wrong gameplan. If Hendo ever fought Jones that would be the most one sided title fight since Mir vs. JDS.
