I look at the current LHW Champion, Daniel Comier and can say with confidence that he can easily coast through some of the bottom 15 guys in the heavyweight like Roy Nelson, Ruslan Magomedov and Big Foot Silva. Hell, he actually coasted through 2 of these fighters with ease and also coasted through Josh Barnett who is currently ranked no. 10 in HW.
I also look at former MW Champion, Luke Rockhold (not using Bisping for obvious reasons) and can say also with confidence that he can easily coast through some of the bottom 15 guys in the LHW division like Patrick Cummins, Misha Cirkunov and Gian Villante.
Same with potential UFC WelterWeight Champion, Stephen Thompson (using him for obvious reasons). I see him cruising through some of the bottom 15 guys at MW like Tim Kennedy, Rafael Natal and Thiago Santos.
Former UFC LW Champ, Dos Anjos can cruise through bottom 15 guys at WW like Albert Tumenov, Tarec Saffiedine and Gunnar Nelson. RDA destroyed Cowboy twice who is now destroying some decent guys at WW. Cowboy decided to move to WW after being wrecked by RDA during their last fight.
However when it come to Conor, the story becomes a little dicey. I have a hard time believing Conor can walk through currently ranked no.14 LW guy, Gilbert Melendez. It's going to be a tough fight for him and he might lose. The same with guys like Will Brooks, Al laquinta and Rashid Magomedov. These are all very tough fights for Conor and there is a likely possibility he might lose.
So back to the question. Is LW stacked with a lot of talented fighters or is Conor not that really talented?
