This is one fight that I honestly didn't see happening at all. I knew it was the logical next step for Gaethje, but I didn't expect for Khabib to pick it up and make it happen so soon. Khabib is like a unicorn now. He gets to choose his fights and seems like he does it sparingly.
As for the fight itself, it's going to be a great one. I think this is one of the best matchups I've seen in a good while. We all know Khabib is an absolute monster in both grappling and on his feet. We also know Gaethje is up to par on most all aspects as well, except for grappling which I don't know of anyone who really comes close to matching Khabib.
This is a really tough one to call. It's really hard for me to picture Gaethje winning against Khabib. Not because I think he's a lesser fighter, but because it's Khabib. It's hard for me to imagine anyone winning against him. Then again, Gaethje absolutely destroyed Tony Ferguson when most people thought he'd lose (not me, I strongly thought Gaethje would win).
Now we're just hours away from seeing what happens. If I had to make a decision I'd say Khabib will remain champion. Gaethje has been known to get ahead of himself and begin to relax when he has any sort of a lead. Khabib will be looking to take advantage of that, take it to the ground submit and tap him.
