As opposed to judo, which desperately tries to stay competitive in securing Olympic mass viewership, meaning that stalling tactics have to be punished at all costs.
Pre-Olympic Judo had much more stalling, right? I can't remember exactly, but I think I've heard that before.
Something about 20 min matches, only scores were waza-ari and ippon, ippon was much harder to score, lots of defensive grip fighting, etc.
I saw Rhadi Ferguson weigh in on FB about the rules. He said that he thinks BJJ will ultimately merge into Judo if you start enforcing stalling the same way. They really did start from the same place, and the main divergence was an early dispute over the rules with a small group from Brazil. If we bring the rules back together, we may end up with the same sport again.
