The problem is there's no simple fix as long as the IJF keeps the stupid AF restriction on leg grabs AND wants to encourage TD attempts. Stand ups from turtle are like the slip rule in freestyle and GR (which also has pros and cons). Turtle is an inferior position so athletes would be much more reluctant to risk attacking if they had to work their way out of a shitty bottom position. Sure it would keep them honest on throw attempts but every high level Judo match would look like Severn vs. Shamrock 2.
Spamming shitty attacks is exhausting and for normal athletes, that's going to deter them somewhat from going overboard. But in the Olympics, we're seeing super athletes with pornstar cardio who could eat a peach for hours or spam shitty seois for days before they get tired.
But yeah, it kills me seeing judoka just going face down ass up in turtle AND top guy not even bothering to attempt to grapple because they're not afforded time to do jack shit on the ground.
Best solution IMO is bring back leg grabs with 3 second time limit before shido, as with other unconventional grips. If a throw attempt results in either tory or uke ending up in turtle, they get 10 seconds of mat time to show progress i.e. top guy turns turtle guy over, is starting to pass guard, progressing toward a sub, turtle guy is wrestling up into a single, etc. And mate + stand up is only called if there's 10 seconds of stalemate with no improvement in position from either man.
