Honestly, it finally makes sense now!
I used to train in judo/sambo for fun before Covid. I got the impression that my Sambo coach never liked BJJ because it felt like it was a gracie propaganda designed to mislead people to the effectiveness of pure ground fighting. But I noticed that more and more, wrestlers/stand up grapplers tend to have insane advantage over ground fighters.
Is it accurate to say that, wrestling and stand up grappling is harder to learn and thus a higher learning curve and yet more rewarding because its a skill not as abundant as ground grappling/BJJ?
I always wondered that when Khabib wore" If sambo was easy it would be called BJJ" since sambo very wrestling heavy.
