Fam what? Did you watch the Barboza, MJ, or Al fight?
Ffs, 1) he outstruck Barboza 89 - 25 and won the fight 30-24, 30-25, & 30-25. Dominant victory.
2) he outstruck MJ 94-19 and although he won by kimura he was easily on his way to another 30-24, 30-25 & 30-25
3) he outstruck Al 134 - 34, and was dominating until he decided to test his striking in the last one which made it look less so but he still won by a completely one-side unanimous decision (50-43, 50-44, 50-43)
All of the above metrics suggest complete one-side domination.
You're right, he ragdolled RDA, but he only outstruck him 36-20 in a 3 round fight (MJ & Barboza were also 3 rounders, and the striking differential is starkly different)
This indicates that 1) not only did he dominate RDA, but he also dominated every fighter you listed as a "comfortable performance" and 2) he is improving over time in all aspects, against fighters with an eclectic range of skill sets, which cannot be proven for Conor because he hasn't had a significant test since Diaz.
As far as him beating fighters light years better than ones Khabib has:
- MJ starched Poirier prior to fighting Khabib
- Aldo was a 13 second wash which doesn't tell us anything in the grand scheme of things
- Alvarez was completely mindfucked by Conor and would lose to any number of current lightweight contenders. He would probably go to a close decision with Barboza for example.
- Holloway is the only one who is markedly better than anyone Khabib has fought & Conor caught him when he was young and on the come-up, the current iteration of Holloway would probably push Conor's shit in.
Khabib can hold top position against Rockhold & wrestle on an even playing field with DC(!!!) Conor cannot train for one year in wrestling and expect to be able to defend against someone as strong and dominant as Khabib. Conor has made his bones cutting massive amounts of weight to 145 & fighting guys who are smaller and physically weaker. Similar to Darren Till. But there's levels to this shit. If he doesn't KO Khabib within one round, he's going to lose. No way he wins a decision.
note - I would 100% bet Covington over Conor. Like, take out loans to be on Colby type of betting. I would convince everyone I know to bet Colby. He's a big, talented welterweight
