Yep, Jones didn't wanna fight him while clean. I've never been more mad watching a fight than when DC was beating him and on the verge of doing something more with that, and got kicked in the head.
Now that DC's done, I think everyone can appreciate that those two guys are the best fighters to have fought each other. They both freight trained everyone else they fought at one point or another. DC has two losses at 40 years old, but the DC that ran a train on the heavyweight division wouldn't have lost to Stipe. And Jones fought that guy twice.
DC's best moment was probably when he completely dominated Josh Barnett after only 10 fights in the game. That was Barnett's 37th fight.
