With all due respect Toxic. I think your opinion of Anderson Silva, is about a valuable as my opinion of Rampage. You hate the guy, and I'm pretty sure no matter what he did, you'd feel that way.
To answer the question, GSP is absolutely not the best P4P fighter. He MIGHT be the best athlete the UFC has, but best fighter? NO way. I would rank Also, Silva, and soon to be Bones, above him, maybe even Shogun and Machida.
This is what im seeing lately. GSP is not even considered a "fighter" because he doesn't engage an opponent how you want him to. You dont win the WW Belt and keep it for this long by doing front flips over opponents. Also he isint a fighter because apparently he also doesent throw any punches or tries to break someone's arm off, and if we thought we see it, its a hallucination.
GSP is THE #2 P4P MMA Fighter on the Planet, you could make a case he is #1, but he is ranked no lower than #2. Aldo, Jon Jones, Cain, etc are not above him. They shouldnt be, at this stage. Silva and GSP are way ahead of Aldo and then the rest of the pack.
They havent fought enough, they havent defended enough and they need more wins against quality opponents, especially in weaker divisions. They need to force people from LW or BW to move to FW to fight Aldo because their is not enough real tests for Aldo. HW turned into a 3 man race. And LHW is no longer the powerhouse it once was just after the PRIDE acquisition. GSP and Silva may not have much new challengers as of late, but the divisions still are pretty deep with plenty of Top Contenders and quality fighters.
Like I said before, finishing shouldnt give you this many extra points, winning should ultimately be more important. Im sure that GSP does think about finishing to silence critics, but what good does that do if he ends up taking a drastic risk, makes a big mistake, and loses? Im not saying he should not take risks, why shouldnt he? But he shouldnt just abandon his gameplan just to make people happy and just start winging overhand punches like he did against Shields. The Janitor just destroyed Brilz in 20 seconds, should he be Top#10 P4P now? Cmon, somewhere the line has to be drawn.
