the only practical way to stop the system is first learning how to work it properly...
when guys like him present their ways to "stomp" positions like rubber guard with them and their assistants barely even understanding the concepts behind the positions, let alone what they're supposed to look like, its pointless. its not helping them, us or anyone else. anyone that trains the system can tell that their ideas are flawed, and they always are.
on the other hand, guys that actually train the system know that the rubber guard isn't invincible and probably understand its strengths and weaknesses more than anyone else, as they have deal with it every day, whether it be utilizing it or defending against it.
if haters like him had half a brain they'd stop preaching their silly ideas that they probably test out on training partners that haven't even seen a real rubber guard before, and they'd ask the guys that actually play proper rubber guards about any existing countermeasures.
