In terms of well roundedness... when u think of guys who excel in almost every category of fighting, those two usually come to mind Striking Fedor - feared power, amazing ability to shoulder roll, slip punches, fast reflexes GSP - super technical, considered by Freddie Roach to be the best technical striker in MMA after Anderson Grappling Fedor - sambo grandmaster with judo. amazing submissions, his arsenal of grappling technique (throws, trips, subs, sweeps) is probably bigger than anyone in mma history. GSP - wrestling alone is what puts him above everyone. had the record for most takedowns until the record was broken by Khabib Nurmagomedov, no shame in that as Khabib himself is a Russian national wrestler & Sambo world champ. GSP easily the 2nd best wrestler in UFC after Khabib. And hes a BJJ black belt. Cardio Fedor - has never gassed out in a fight, gone to decision before, for a chubby heavyweight, his gas tank is impressive GSP - also never gassed out in a fight, known to be the most athletic fighter in MMA history (with exception of maybe Brock Lesnar who some argue as the best athlete) Speed Fedor - known for his quickness and agility as a heavyweight, his physique makes it more impressive! GSP - fastest jab in MMA. super athlete, the guy is like a cat Ground and Pound Fedor - took the sport by storm with his GNP of heath herring and nogueira.. some of the most vicious in the sport, so much power he can generate from short punches on the ground GSP - not much of a finisher, but man he makes peoples faces look like a mess with his constant pace and non stop GNP when he gets takedowns (see BJ Penn part 2) are there fighters who are more complete than these guys? i can think of some fighters who might contend? Weidman? Cain? BJ Penn (in his prime)?
