Well lets compare GSP to Fedor p4p. Since people call Fedor the p4p best just because of his record.
Fedors wrestling doesn't even compare to GSP p4p.
Fedors strikes, although powerful don't show nearly as much skill and technique as GSP. I mean when is the last time Fedor threw a switch kick or a spinning backfist or superman punch?
GSP's BJJ vs Fedors Sambo. Well i just look at it as overall ground game. GSP has submitted guys like Hughes and Trigg with little effort, Fedor has tapped some great guys too but nobody that compares to Trigg or Hughes p4p.
Fedor might be tougher,and have a better chin. But p4p skill wise GSP blows him away..
I agree with GSP being the best p4p but these are terrible arguments. The only legitimate point you have is about GSPs wrasslin.
