Conditioning looked terrible. REAL bad. That's the worst I've ever seen his conditioning look. He looked slow. He still can't learn to keep his chin down. He needs a tennis ball under his chin. His striking was even sloppier than it's normal sloppiness (didn't even think that was even possible). Terrible fight IQ too. When it was apparent he couldn't match his standup, he should've went for more level changes but still chose to stand.
His striking was mixed
On the one hand, it was very sloppy at times, especially that overhand right, one of the worst ive ever seen.
But then hed have moments where he'd throw nice jabs, left hooks, even a straight right with good form when thrown in a combination.
He would have moments as well where he slipped / rolled and moved his head very well, very defensively responsible, then other moments where he'd be sloppy and let low hanging fruit punches get through.
Bit of a mixed bag of everything.
Overall, considering its his 2nd big fight at the highest level, it wasn't too bad though.
Standing 5 rounds with Gaethje and holding his own is impressive in itself. Especially since most expected him to have his success in the grappling.
If he continues improving, and is able to stabilize / tap into that more technical and defensively sound version of himself on a more consistent basis, he's still someone to watch as a future contender.
