Correct, most BJJ competitors arent spending lots of time practicing Judo and back exposure throws because it only awards 2 points, 90% of matches are on the ground, so practitioners create stratagies to win the match, and not by Ippon. Where in Judo, the name of the game is to throw your opponent onto their back, which changes the game. Luckily i came from a Judo background and i have good stand up game, but for the majority of todays competitors, playing judo when your judo is weak is a risk, and again why spend alot of time on judo when its only 2 points. Also, when it comes to MMA, these again have differnt rules of engagement, therefor its more useful to learn these throws. It all comes down to creating the most efficient stratagy to win a match based off the rules of engagement for said sport :) And just to clarify, this class video is for those who dont have a stand up game to begin with, its a good place to start :)

Same thing with uchi mata. A lot of bjj folks think uchi mata is too weak on its own and just use it to set up ankle pick or single leg. But that’s bc they’ve never been dominated by a strong uchi mata player cos holy shit that will rattle you. Wish more ppl were willing to dedicate time to judo so they can see what high level judo feels like.
