Once Maia retires...

[DanAndroid]

Danis, Kron, Ryan Hall. Thats all I can think of off the top BJJ wise. Would Askren be considered a specialist?

 

[Fahcough]

And you're also twelve.

I am 1. The 12 follow me. You have been blessed, scurry back to your hole.

Yes, there will be the Dillons and Krons of life. But a highly successful semi-pure BJJ MMA fighter? There will be none.

DIllon is not remotely on Kron's level when it comes to BJJ.
And that's not an indictment of Dillon

Let's make this clear when it comes to BJJ

Jake stayed in Maias game and won. Ben could hell yeah.

Wanna see something wild?

 

[ScholarDayo]

Claudio Silva is lethal on the ground

 

[Arne Rud]

Kron Gracie?

he is the best grappler out there

 

[Persuadertron]

Wanna see something wild?

Badass. That was trippy that small guy Mendes never seen him before. Jake was exhausted hah.

 

[cheesus]

Lots of guys.

Khabib a submission wrestler.

Conor a boxer.

Adesanya a kickboxer.

Colby the wrestler.

Ngannou the athlete.

You just won’t have any BJJ specialists at the top levels because BJJ sucks.

None of those guys are really specialists. They all have some ability in cross training. Khabib has extensive training in judo, submission grappling, sambo/combat sambo, his striking is wild but effective he is well rounded. Israel had competed in muay thai, kickboxing, boxing before crossing over to MMA and is a BJJ blue belt and Colby has relied on boxing and brawling in the past.

My pick would be Askren, the guys striking isn't much past the ability of Dan Severn.

He actually rocked Maynard with some of those kicks, not that rocking Maynard is a surprise these days.

This gif isn't the best example, but I remember thinking the same thing.

 

[Rational Poster]

Maia isn't one dimensional. He has really worked on his wrestling and especially his boxing during his decade plus with the UFC. It is a bit hard to progress further since he started these changes in his 30s.
I think the most one dimensional/specialist guy is probably Askren. Even someone like Hall has a serviceable odd striking game that serves to frustrate his opponent and allows Hall to implement his game. On a side note, someone I always found lacking in "technique" and one dimensional is Hands of Stone. He is smaller than everyone in his division, he doesn't seem to know how to grapple well but he finds a way to win due to overwhelming power. Even his striking isn't that clean looking.

Actually I think it would be fair to attribute Maia's late career resurgence to improvements in his wrestling and takedowns.
