WATCH: Kade and Tye Ruotolo offer a preview of what their matchup would look like with a sparring session at RVCA

ONE lightweight submission grappling world champion Kade Ruotolo and his brother Tye Ruotolo are two of the most formidable athletes in the sport today. All you need is one glance at how they fight and you'd know that this statement is true. The prodigious twins are the perfect combination of clean technique, frenetic pace and insane athleticism.

In a video released on the Ruotolo brothers' Instagram account, we saw Tye Ruotolo and his brother Kade going at it in a grappling sparring session. One thing that sticks out right away is how intense they are and how relaxed they are at the same time. The dizzying pace that the two operated at, while still not going 100%, is quite impressive to watch.

Here's the clip:

"Rolls at Rvca"

This could be a preview of what it would look like if Tye and Kade Ruotolo decided to face each other in competition. They pretty much spent the majority of their lives sparring with each other, which means they know each other's techniques and tendencies like the back of their hands.

This reminds us of another set of grappling twins, the Miyao brothers, who famously faced each other at Abu Dhabi Mundials back in 2013. Paulo and João Miyao went at it, counter after counter, until the time expired, with João narrowly getting the referee’s decision.

Tye Ruotolo to face Reinier de Ridder in submission grappling superfight at ONE Fight Night 10

At ONE Fight Night 10, Asian martial arts organization ONE Championship will have their first event live on American soil. The historic fight card is shaping up to be their biggest yet since their 10-year anniversary card, ONE X.

One match to watch out for is a submission grappling superfight for the ages. Tye Ruotolo, one-half of Jiujitsu's grappling prodigies, the Ruotolo brothers, will lock horns with former ONE light-heavyweight and current middleweight world champion Reinier de Ridder.

Though there's a clear size difference between De Ridder and Ruotolo, not everyone is seeing it, considering what Ruotolo did at the ADCC World Championship last year.

Tye Ruotolo faced and beat bigger men, Felipe Pena and Nicholas Meregali, and gave them a run for their money. Tye beat Pena while Meregali barely scraped by with a win. Both grapplers outweighed Ruotolo by at least 60 pounds.

In fact, it was the hyper-aggressive Tye Ruotolo who called out De Ridder back in December. As for the ONE middleweight world champ, 'The Dutch Knight' is one of the most successful ground specialists in MMA, going undefeated for a few years based on his sheer expertise on the ground alone.

De Ridder is no stranger to submission grappling superfights, however. He went to a draw against Ruotolo's own mentor and ADCC legend, Andre Galvao, at ONE X last year.
