When is the last time you guys watched Khabib/Barboza?
I just did, and holy shit did I remember it wrong. If you haven't seen it lately, I recommend watching it again.
I had it in my mind that Khabib really beat Edson down for 15 minutes, but that's just not how it went. He beat him down the second half of round 1 but in terms of actual real damage that was when the majority of it happened. First half of round 1 was standing, second half was a beatdown. Round 2 Khabib took awhile to get the TD, then held Edson down and landed some gnp, but nothing hugely significant.
Round 3 is what I really, REALLY remembered wrong. About a minute of striking, nothing significant. Then Khabib pushes a broken and exhausted Edson against the cage (aided by Edson kind of just backing up into it). Khabib then holds him there, and twice tries to level change for TD's. Somehow even the corpse that was Edson at that point stuffs both attempts and spins off the cage (that whole sequence taking maybe 90 seconds). More striking with Edson throwing desperation spinning kicks and stuff. Khabib again pushes him against the cage with about 2 minutes left. This time does get the TD. Edson squirms and Khabib tries to hold him down and does for awhile, but lands nothing. With about 30 seconds left Edson is able to finall wriggle free and get back to his feet, where the last 20-30 seconds tick away with a bit more striking. I really thought Khabib put it on Edson in round 3 (even if Khabib did slow a little). But man, even though Khabib clearly won the round, it is an eye opener that he didn't have enough to get a broken version of Edson down the first 2 times he tried, and wasn't able to hold him down and do anything offensively when he finally did get the TD.
If Tony survives rounds 1 and 2 and is relatively fresh and we see the version of Khabib I just watched in round 3 of that fight, I think Khabib is in serious trouble. Tony will pour it on him and it will turn into a beatdown.
Maybe we see Khabib with more to offer, or somehow he manages to make Tony look as broken as Edson looked. But if not, I honestly don't see how Khabib even survives to see the final bell.
