After the Burns fight UFC and Dana were all over him and they gave him the Nate fight exactly to cement him as a rising star and then give him the title shot because everyone knew he would murder Nate.
It was his first and still the only event he was set to headline and it was against a very known and popular fighter. But he really did messed up on that weight cut and a concern for lack of professionalism was raised. So they forced him to forget about welterweight and focus on middleweight only and kinda reset his title run there
Having him to fight one more fight after Burns in order to give him a title shot was reasonable. The weight miss and subsequent health issues is what really slowed his career down
I do agree that he should fight for the MW belt next over Sean
IMHO, he was assigned the Nate fight to be an executioner. They clearly wanted to diminish Nate's bargaining power with a lopsided loss as he left the company, which is their standard MO as most fans know.
But it blew up in their face. Fans turned against them for it, ESPN turned against them and said it was a bullshit match... literally everyone did if you remember from back then. It was unanimous in the PR and WME realized that early on it became a PR nightmare. Nate became the martyr and UFC the villain. But they already announced the fight and were screwed.
So they had to undo the damage they were taking and not say "we suck and realize we suck, our bad." So read my point #7... because there was A LOT of weird shit with that card. Most weird shit of any card ever, and it is hard to ignore.
1. A clear lie regarding "biggest brawl in UFC history" they used to justify changing it to Khamzat vs Kevin
2. Tony booked at 170 for literally no reason (so yes I'm saying booking him at 170 they already knew they'd change the event to him vs Nate)
3. Kevin booked at 180 for literally no reason / Rodriguez booked at 180 for literally no reason
They had the narrative down as soon as they realized they needed to bail. Their "doctor" (probably a fucking PR guy wearing a labcoat, who the fuck knows) would tell Khamzat the UFC "ordered" him to rehydrate (confirmed by Khamzat). They weigh him and, like literally any fighter on the roster, rehydrating the gallon of water (which is 8.34 pounds) puts them 8 pounds over. Tony vs Nate, Kevin vs Khamzat (super dangerous for him to fight without dying until he drank a gallon of water but then he's all good, right "doctor"?), Li vs Rodriguez. How neat and tidy. Oh, and it is all Khamzat's fault. And the fans literally ask no questions and turn on Khamzat... don't ask why the "brawl" story (supposedly between 20 pro fighters and the "worst ever" event in UFC history) resulted in literally no injuries, no scratches and no footage despite multiple cell phones and UFC camera crews catching the part where Khamzat and Kevin yelled at each other that supposedly set it off... guess they all turned off 10 seconds later huh? No fan ask about the utterly bizarre weight class declarations made more than a month before the event (ie: when UFC realized they were already axing the card once they took heat from fans/ESPN).
Khamzat was made the fall guy for their decision and that "fall guy" act justified:
1. a weight class change
2. 0 title shots despite it being on lock after he beat #2 ranked Gilbert in a FOTY, and ultimately
3. years of inactivity
4. all fans showing they have no fucking clue how weight cutting works when they lambasted him for years for being "a whole 8 pounds over!!1!" despite it being made public he was ordered by a UFC doctor to rehydrate... literally every non-HW would be over the limit by the same amount if they did this
Also robbed us of double belt status and legendary fights as Khamzat would have fought both Kamaru and Izzy. All because UFC wanted to throw a fighter under the bus for their shitty matchmaking.
