He would beat the strikers and lose to the grapplers.
Cormier, Cain, Barnett and any powerful wrestler would beat him.
He's a better striker than JDS so Anderson V Junior on the feet most likely = a victory for Andy.. considering Anderson would be 6'2 230lbs with 78inch reach and JDS is 6'4 240lbs and same reach.
I dunno if Werdum, Bigfoot Mir, Big Country etc. have the speed to take him down, Anderson's movement is excellent and he has equal reach to pretty much everyone in the division.
I know i'm a huge Anderson fan but I feel like i'm being fair, what do you guys think?
