In the current MW division, there are 5 potential title challengers out there right now who have both the opportunity to earn a shot, and the possible skill sets to beat Anderson. None of these fighters should be favored to beat Anderson. But eventually, someone will get lucky, or Anderson will slow, or someone will see something on tape and exploit it. Of all fighters out there, this list contains the fighters currently most likely to be the one to do it.
Weidman - Pros : young, confident, athletic and an insane wrestler. Cons : lacks experience. Some might argue he isn't seasoned.
Munoz - Pros : decent MMA wrestler, heavy hands, entering his prime. Cons - despite his pedigree, his wrestling hasn't been anywhere near Chaels in the past in the cage, slow hand speed, and may not fight Anderson due to being teammates.
Evans - Pros : great MMA wrestler. Phase shifts well. While fresh, has speed and power. Very experienced and a former champion. Cons - has been out struck by deceptive, fast strikers in Jones and Machida before, has chin questions, may lose the speed advantage he usually has, been known to gas. He has never cut to MW before.
Rockhold - Pros : has the "phenom factor" of Cain, Aldo, Jones etc, extremely athletic and talented striker. Large for the division. Gaining experience and entering prime. Comes from one of the best camps in the sport. Cons : Other than his fight with Souza, there is a palpable dearth of top talent on his resume, which gives him an experience disadvantage. Likes to strike, which automatically makes Silva, who has borderline super human reflexes a bad match up.
Lombard - Pros : Explosive, high caliber athlete with great takedowns from the clinch, and tremendous power. In his absolute prime and has a 12 minute long highlight reel of nothing but destruction. Very experienced. Cons : short reach, despite experience against cans/decent/lower-mid level guys, has not faced a lot of truly elite talent.
Honorable mention goes to Bisping : Pros - he has a good, well rounded game and a lot of high level experience. Cons - he has a lack of power, likes to strike, has shown his chin is not bullet proof.
Which of these fighters will be the one to unseat Anderson? Will it be someone else? Will he beat all of these guys anyway?
(disclaimer : I know anderson would be favored to beat any of these guys and I would pick him to beat any of them tomorrow, but someone is bound to do it. This is simply for the sake of discussion. )
