With great champions like Usman and Adesanya dominating the game today at WW and MW, it's easy to make comparisons to GSP and Silva. This may be common opinion, but I believe that the # of Title Defenses are what signify where you rank all-time in your respective division, and also P4P. Reason being is that every title defense you win symbolizes you being the best fighter in the division at that time. It's the only measurement that can really withstand the test of time as our sport evolves because fighters/athletes evolve. Usman may be beating better competition than what GSP faced, and likewise the WW champ of 2035 (probably Erick Silva) is going to be beating competition far better than what either of them faced. Looking only at WW & MW for this discussion, here are the top 3 title defense record holders in each weight class: WW GSP - 9 Hughes - 5 Usman/Woodley - 4 MW Silva - 10 Adesanaya - 3 Weidman - 3 I'm a big fan of both Usman and Adesanya, and cheer for them to win most of their fights. I also think that it's incredible to have two champions as active as they have been. They still have some ways to go before we can compare them to GSP and Silva.
