P4P is pure opinion. I could say Clay Guida is P4P the best fighter in the world, and it would mean as much as saying Anderson Silva is. The only thing that matters is who is the best of the division.
I disagree with this. You can't figure out an absolute best, but as it always comes down to a select few, there must be some discernible criteria for determining who is the best. You can't claim that you can claim any fighter the best and have equal validity to certain other fighters.
