I really question how good Gaethje is, good enough to give tough guys a challenge? Absolutely but none of his wins have aged well?
Michael Johnson? (Was top 10 at the top but really has always been an incomplete journeyman with talent at best and he beat the shit out of Gaethje and had war before fading, Gaethje out toughed him)
Then he lost to Alvarez and Poirier by TKO in brutal fights where he took an ass kicking.
Then beats Vick, Barboza and Cerrone in round 1
Vick was never anything relevant or talented, that was a rebound lob for Gaethje to spike.
Barboza is chinny, a fringe top 10 guy at best and responds poorly to pressure, a perfect matchup for Gaethje
He beat up the ghost of Donald Cerrone.
Now he fights Tony who's pushing 37 and clobbers him, its a bit of revisionist history, he earned a title shot beating Tony fairly squarely but it's not outrageous to ask it Ferguson was losing some steps at this point?
He got handled by Khabib with ease
He had a war with Chandler where he was rocked and hurt a bunch, very competitive fight. Chandler is super athletic, fast and dangerous for the first 5-7 minutes but Hes also an old battered Lightweight who I suspect loses to a lot of the top 10.
Charles vs Poirier will be interesting, so will Gaethje vs Charles if Charles pulls it off (which I think he does). Islam vs Charles will be the best fight at LW in a long time.
