Sean Strickland Just Complicated the Middleweight GOAT Conversation

Sean Strickland beating Khamzat Chimaev did not just change the current UFC middleweight rankings.

It changed how we are allowed to talk about Sean Strickland historically.

Before UFC 328, Strickland was already one of the weirdest champions in modern MMA history. He had the Adesanya upset, the awkward defensive style, the volume boxing, the pressure, the personality, and the sense that his title win was still somehow treated like a disruption instead of a career-defining achievement.

Now that is harder to do.

Strickland defeated Chimaev by split decision at UFC 328 to reclaim the UFC middleweight title, handing Chimaev his first professional MMA loss and becoming UFC middleweight champion for a second time. The result was close, controversial to some, but legitimate enough to immediately move Strickland back to the top of the division. ESPN’s updated divisional rankings now list Strickland as the UFC middleweight champion, ahead of Chimaev, Dricus du Plessis, Nassourdine Imavov, and Caio Borralho.

That matters because middleweight history is not just about who was the best on their best night.

It is about who beat whom, when they beat them, how long they stayed at the top, and whether their wins still mean something when the division moves on.

And after this win, Strickland has forced his way into the all-time top ten conversation.

The Problem With Ranking Middleweights

Middleweight is one of the strangest legacy divisions in MMA.

At welterweight, the debate is clean: Georges St-Pierre is the standard. At lightweight, the argument is crowded but understandable. At heavyweight, chaos is part of the history.

Middleweight is different.

The division has one obvious king, a second modern king, a group of great champions with flawed resumes, and then a long list of fighters whose careers depend heavily on what you value.

Do you reward title defenses?

Do you reward peak skill?

Do you reward strength of schedule?

Do you reward longevity?

Do you reward beating the best middleweights, or simply being the best fighter who ever happened to win a middleweight belt?

That last question is why someone like Georges St-Pierre creates a problem. He beat Michael Bisping to win the UFC middleweight title at UFC 217, but his middleweight resume is one fight. Historically important, yes. All-time middleweight resume, no.

The same kind of question follows Alex Pereira. He beat Israel Adesanya for the belt, became champion, then moved up and became even more historically important at light heavyweight. But as a pure middleweight, the resume is short.

That is why Strickland’s new win matters. He is not just a flash champion anymore. He is now a two-time UFC middleweight champion with wins over Israel Adesanya and Khamzat Chimaev.

That is real historical weight.

My Updated All-Time Middleweight Top 10

1. Anderson Silva

Still the standard.

Anderson Silva’s case is simple: longest reign, most iconic peak, most title defenses, most fear. His run was not just dominant statistically; it changed what people thought elite striking could look like in MMA.

The knock against Silva is that his later losses made the ending ugly. But legacy is not built only on the ending. At his peak, Silva made elite fighters look like they were operating on a different clock.

He is still the middleweight GOAT.

2. Israel Adesanya

Adesanya is the clear number two.

He had five successful title defenses during his first UFC middleweight reign, became a two-time champion, and beat Robert Whittaker, Paulo Costa, Marvin Vettori, Yoel Romero, Jared Cannonier, Kelvin Gastelum, and Alex Pereira in the rematch. UFC’s own career retrospective credits him with five successful defenses from 2019 to 2022.

The losses hurt him more now than they did two years ago. Strickland beat him badly. Dricus submitted him. Pereira stopped him. The aura is gone.

But the resume is still massive.

Adesanya’s argument over Anderson is mostly skill-based: deeper athlete pool, more modern tactics, better defensive wrestling era, cleaner kickboxing translation. But historically, he still falls short because Anderson’s reign was longer and more culturally dominant.

3. Robert Whittaker

Whittaker might be the most respected non-GOAT middleweight ever.

He does not have the same title reign as Anderson or Adesanya, but he has one of the best strength-of-schedule resumes in the division’s history. Yoel Romero twice, Jacare Souza, Derek Brunson, Jared Cannonier, Kelvin Gastelum, Marvin Vettori, Paulo Costa — Whittaker spent years fighting monsters.

His problem is simple: Adesanya beat him twice.

That blocks him from the very top tier. But as a pure middleweight body of work, Whittaker is still above almost everyone.

4. Chris Weidman

Weidman’s prime was short, but it was historically enormous.

He beat Anderson Silva twice, defended against Lyoto Machida, and defended against Vitor Belfort. That is not just a title reign. That is a reign built on ending an era.

The second half of his career damaged how people remember him, but it should not erase what he actually did. Weidman is being inducted into the UFC Hall of Fame’s Modern Wing in 2026, with his Silva wins and three successful title defenses central to that recognition.

Peak for peak, he belongs high.

5. Sean Strickland

This is where the conversation changes.

Before the Chimaev win, Strickland was probably somewhere around the back end of the top ten. He had the Adesanya win, the belt, the Paulo Costa win, and a strong UFC career, but there was still a feeling that history could treat him as a one-night disruption.

Not anymore.

Strickland is now a two-time UFC middleweight champion. He has beaten Israel Adesanya and Khamzat Chimaev in title fights. He also stopped Anthony Hernandez earlier in 2026 before reclaiming the belt, adding another relevant win in the current era.

His case is not dominance.

His case is disruption.

He beat the artist in Adesanya and the monster in Chimaev. Two totally different threats. Two totally different kinds of legacy wins.

That is why Strickland jumps.

6. Michael Bisping

Bisping’s greatness is not about being the most skilled middleweight ever.

It is about survival.

He fought through multiple eras, beat Anderson Silva, knocked out Luke Rockhold on short notice to win the belt, and defended against Dan Henderson. His title reign was not the strongest, but his longevity and historical footprint are impossible to ignore.

Bisping is the bridge between eras: tough enough to survive the old middleweight chaos, smart enough to capitalize when the belt finally became available.

7. Dricus du Plessis

Dricus is hard to rank because his career still feels unfinished.

But the resume is already serious. He beat Robert Whittaker, Sean Strickland, and Israel Adesanya.

That is a ridiculous three-name stretch.

The reason he is not above Strickland now is because Strickland has reclaimed the belt and added the Chimaev win. But Dricus still has a direct win over Strickland and a win over Adesanya, so the argument can absolutely be made that he should sit higher.

If Dricus wins the belt again, or beats Strickland again, he could move into the top five quickly.

8. Luke Rockhold

Rockhold at his best was terrifying.

His win over Chris Weidman was one of the best title-winning performances in middleweight history. Before that, he had already been Strikeforce champion and had beaten names like Jacare Souza, Tim Kennedy, Michael Bisping, and Lyoto Machida.

The issue is longevity at the top.

Rockhold’s peak was elite, but the fall was steep. Still, his best version was one of the most dangerous middleweights ever.

9. Yoel Romero

Romero is the greatest middleweight to never win the UFC belt.

That sentence explains both the case and the limitation.

He beat Chris Weidman, Luke Rockhold, Jacare Souza, Lyoto Machida, Derek Brunson, and Tim Kennedy. He fought Whittaker twice in brutal, razor-close fights. He was physically unlike almost anyone the division has ever seen.

But without the undisputed UFC title, he cannot be ranked above the champions with comparable resumes.

He is the ultimate “eye test vs. achievement” fighter.

10. Alex Pereira

This one is complicated.

As a complete MMA figure, Pereira is bigger than this ranking. He beat Adesanya, won the UFC middleweight title, moved up, and became a historic light heavyweight champion.

But this is an all-time middleweight ranking.

At middleweight, his resume is short. The Adesanya win is enormous.

 The Strickland knockout aged well. But he did not defend the middleweight belt and left the division quickly.

So he belongs in the top ten, but not above fighters who built longer middleweight resumes.

The Cases for GOAT

The Anderson Case

Anderson Silva is the GOAT if you value reign, dominance, aura, and historical separation.

He was not just winning. He was embarrassing contenders. He made title fights feel inevitable. Middleweight before Anderson and middleweight after Anderson are two different things.

The argument is not that he fought better athletes than today’s fighters. The argument is that he separated from his era more than anyone else has separated from theirs.

That is what greatness usually means.

The Adesanya Case

Adesanya is the GOAT if you value modernity, technical depth, and level of competition.

He ruled in a more developed sport. He fought better-prepared athletes.

His striking game was not just flashy; it was systemized, layered, and repeatable. He beat Whittaker twice, shut down Costa, handled Vettori twice, beat Cannonier, and avenged Pereira.

The issue is that his losses are too loud.

Strickland did not just beat him. He solved him in a way that damaged the mythology. Pereira stopped him. Dricus submitted him.

Adesanya can still be argued as the best middleweight ever on skill, but not as comfortably on legacy.

The Whittaker Case

Whittaker’s GOAT case is the purist’s case.

He did not have the long reign, but he fought killers for years and remained elite across multiple versions of the division.

The problem is that GOAT cases usually need a throne. Whittaker had the belt, but he did not get the defining reign. His losses to Adesanya keep him just outside the real GOAT debate.

He is more “greatest contender-champion hybrid” than greatest middleweight ever.

The Strickland Case

Strickland is not the GOAT.

But after beating Chimaev, he now has one of the strangest elite cases ever.

He beat Adesanya when Adesanya was still viewed as the division’s technical king. Then he beat Chimaev when Chimaev was viewed as the division’s physical takeover threat.

That gives Strickland something very few fighters have: two wins that interrupted two different narratives.

He is not the most dominant middleweight ever. He is not the most athletic. He is not the cleanest finisher. He is not the most decorated.

But he may be one of the most historically inconvenient fighters the division has ever seen.

Every time the sport tries to move past him, he makes the division answer to him again.

The New Top 10 Debate

The most controversial part of this list is Strickland at number five.

Some will say that is too high because he does not have enough title defenses. That is fair.

Some will say Dricus should be above him because Dricus beat him and beat Adesanya. That is also fair.

Some will say Bisping, Rockhold, or Romero had deeper careers. Depending on the criteria, that argument is not crazy.

But Strickland’s two title wins are not ordinary title wins.

Adesanya was not just a champion. He was the defining middleweight of the post-Anderson era.

Chimaev was not just a contender. He was undefeated, feared, and seen by many as the next dominant force.

Strickland beat both.

That has to move him.

What Strickland’s Win Really Means

Sean Strickland did not become the middleweight GOAT by beating Khamzat Chimaev.

But he became impossible to leave out.

That is the real shift.

His career is no longer just “the guy who upset Adesanya.” It is now a two-title-run resume with wins over two of the most dangerous middleweight archetypes ever: the elite striker and the undefeated grappling pressure machine.

Middleweight history used to have clean tiers.

Anderson and Izzy at the top.

Whittaker, Weidman, Bisping, Rockhold, Romero, Pereira, Dricus, and others fighting for placement underneath.

Now Strickland is right in the middle of that argument.

Not because his career has been perfect.

Because his best wins are too loud to ignore.
