Demetrious Johnson picked the right target this week. Then he swung at it with the wrong arm.
In a clip Ariel Helwani posted on X on Oct. 12, the former UFC flyweight champion argued that MMA should handle oblique kicks the way the NFL handles hits on the quarterback. “You cannot rough the quarterback because they want to make sure the quarterback has a long career. I see it the same way for mixed martial arts,” Johnson said. He opened with the line that should have carried the whole case by itself: “It can ruin somebody’s career.”
That’s correct, and frankly it’s enough. Somewhere in the middle of the clip, though, Mighty widened the net, and the extra weight dragged a good argument into a fight it didn’t need.

The tap rule is his best idea
Here’s the part of Johnson’s reasoning that should be printed and taped to the wall of every athletic commission office. He said he won’t throw oblique kicks or hunt heel hooks because he has other ways to finish people. Then he drew the line that matters: “I’ll break somebody’s arm because you have an opportunity to tap, right?”
That’s a real principle, and a useful one. An armbar gives the other guy a vote. He feels the elbow straighten, he makes a decision, he either taps or he gambles. An oblique kick gives him no such vote. Josh Barnett, replying to Helwani’s clip on X, described what happens when the kick lands clean: the knee gets driven backward with high kinetic force against the cartilage, tendons, ligaments and bone, causing what he called immediate and potentially life-altering damage. Nobody taps to that. It’s over before the brain files the report.
So by Johnson’s own standard, the oblique kick fails the test. You don’t need the NFL comparison, you don’t need a speech about legacy. A technique that can end a career with zero chance to surrender is a problem, and Mighty explained why better than most people who have tried.
Then he brought heel hooks into it
This is where it unravels. Johnson put heel hooks in the same bucket, and he got moral about it. “But heel hooks and stepping on somebody’s knee, for me, it’s like dirty. I don’t like the technique. I don’t teach that technique.”

A heel hook is a submission. It has the tap window he just praised. Barnett went straight at that, calling the comparison “so close, yet also false equivalency.” His breakdown: a heel hook loads both the ankle and the knee, which spreads the pressure across more than one joint and usually less violently than a kick does. “In many cases, the ankle likely is the first point of injury and very recoverable,” Barnett wrote. He argued Johnson was picturing the worst version of the hold, cranked explosively with intent to rip before the opponent can tap or the ref can step in.
Barnett even met him halfway. He said heel hooks could reasonably be banned at amateur events for safety, then drew his own line: “This isn’t an amateur event we’re arguing about BTW, but professional prize fighting.”
And then the postscript, which landed like a body shot. Barnett pointed out that Johnson’s coach, Matt Hume, coached Barnett first, and that Hume “is a master at Heel Hooks.” Barnett said they trained the hold constantly at AMC. His conclusion was fair rather than nasty: Johnson is stating a personal preference, which is fine, but a preference shouldn’t be treated as a case for regulation.
Split the argument and it wins
I’m with Johnson on the kick and with Barnett on the hold, and those two positions don’t conflict at all. They fit together.

The word “dirty” is what hurt Mighty most here. Dirty is a feeling. Career length is a measurable thing, and it’s the exact frame he borrowed from football. The quarterback rule he cited exists to keep a guy on the field for years. Apply that standard honestly and the oblique kick is the obvious candidate, because the fighter on the receiving end has no defense once it’s committed and no exit once it lands. The heel hook gets cut from the list by the very sentence Johnson used to defend armbars.
It’s been a loud week for him. He told Helwani that Sean Strickland signed his contract and should either fight it out or walk away to boxing, a take MMA Mania called a big oversimplification. Kayla Harrison, also via a clip Helwani posted, said “I’m just kind of over Mighty’s attitude” after his comments about Natalia Silva and Wang Cong. MMA Mania has described him as a content creator whose takes keep getting hotter.
This one deserves to be separated from the noise, because underneath the heel hook detour sits the most defensible idea he’s put out all month. A fighter who can’t tap can’t protect his own career. Johnson said that himself. He should drop the heel hooks from the pitch, keep the quarterback line, and say it again louder.
