Ok, let's get technical since you want to talk shit. You say this is a great fight due to both of their "collective dominance and skillsets as mixed martial artists"? Jones is great in everything, literally has the deadliest arsenal in the game. DC is a wrestler who uses his grappling more than anything else. His striking and ground game is nowhere near Jones's.
Who has DC fought at 205 that is so great that can compare to the legends Jones has ran through? Hendo is the only one. He beat the shit out of Cummins but what top contender wouldn't? It would be one thing if DC dominated the likes of guys like Rashad, Gus, Rumble, Glover, Machida, Shogun, or Vitor. But he hasn't. So how can you say this is a "great" fight and even compare Jones and DC based on their resume (collective dominance) and skillsets when Jones blows DC out of the water.
DC can make it interesting and potentially pull off an upset, but it's not "THE" greatest LHW fight of all time. If that was the case Lyoto vs Jones would be the greatest LHW fight of all time based off of the skillset of an mixed martial artists , Jones vs Lyoto would have been the greatest LHW fight of all time.
Why are you so caught up at how many times DC has fought at 205? We're supposed to ignore what he did at HW?
DC has great boxing and some of the best grappling I've ever seen in MMA. If you think otherwise, great. Most of the people with opinions I care about agree that this is the greatest collection of talent between 2 fighters stepping into a UFC cage to fight at LHW.
Machida vs. Shogun I is one of the most underrated fights of all time. The final decision was incorrect, but the aggregate technical skill exhibited by both fighters is near the top of any fight in any division.
Weidman (2013) and Rampage (2007) brought TRUTH to massively over-hyped "champs" in ankle-deep divisions... and pain to fanbois. Shallow divisions breed illusions.
