If for some reason Khamzat got the (unearned) titleshot against Adesanya, it would had most likely ended with a quick finish like Khamzat vs Rob or Khamzat vs Kevin Holland. Consensus before their fight was that Rob had the best defensive wrestling in MW.Your right about the "levels"
Strickland has been a Champion and is a title Challenger.
Khamzat has pretty much beaten only one ranked opponent in his career.
They are not at the same level.
Kamzat has promise.... But face it... Any other fighter with his record and actual accomplishments would still be considered a prospect.
You stop being a prospect when you win against top 5 fighters, which Strickland never did before his titleshot. Khamzat beat Burns, Usman, and Rob. Lee Jingliang was also ranked, Holland has also been ranked.
He has basically won 3 number one contender fights; Burns, Usman and Whittaker.
Usman took the Khamzat fight because he really liked his chances against Strickland, considering how their fight at WW went.
Strickland in the same situation lost to Pereira and Cannonier.
Khamzat has never lost a fight or a first round, Strickland has 8 split decisions and 6 losses, and lost round 1 vs unranked Abus in the fight before his titleshot. He's also never finished an opponent who was ranked at the time. Different level, indeed.
