Rener and Ryron Gracie are becoming regulars here at DSTRYR/sg because they consistently put out educational and fun video content for the grappling mammal. It's like we're on our own special Gracie Diet of UFC breakdowns and smoothie instructionals.
You watched 129. We assume this, because you are here at DSTRYR/sg. That means you saw relatively unknown Pablo Garza slap on a wicked flying triangle in Round 1 of his fight against Yves Jabouin. This kid has great submission chops, having racked up 7 subs in 11 fights (with only 1 loss). Great finish. Leave it to the deep undercard to deliver the good stuff.
So, watch Rener/Ryron break it down for you, followed by 5 minutes of Gracie Combatives DVD sales. We can't blame them though. Gracies gotta eat too (and the Gracie Diet doesn't permit the consumption of $5 Footlongs).
