People can think whatever they want about what JDS or Bones are going to accomplish in the next few years, but anyone who's been watching this sport for more than a few years knows there is a steady stream prospects who come through the ranks and build a huge bandwagon of fans. In the time I've been watching the UFC, I can remember Sylvia, Mir, Arlovski, Lesnar, Gonzaga, Vera, and Cain all being talked about in much the same way as JDS is now. None of them accomplished anything close to what Anderson has, nobody at HW has in the UFC. I would be shocked if JDS manages to get passes Werdum, Cain, and Overeem without a loss.
Bones is maybe a different story, since nobody has ever really done what he has done. In the same breath though, usually the guys who dominate like Bones get figured out at some point. Shogun and Machida both were supposed to dominate for years but people figured out ways to beat them.
What I'm saying is it's hard to really understand what Anderson has done in the UFC. 15 straight wins and 10 title defenses are both records that nobody has ever come close to. GSP who's been dominant for years has 6 defenses, Hughes has 7 split over 2 streaks. Those are the only 2 guys who got more than half as many as Anderson. The UFC has never had anyone like him, but there have been plenty of guys who got hyped like Bones and JDS but never delivered.
