I think his bjj was fine. He was always all about mastering the basics.
Guard is just different in mma. Guys don’t even try ti pass your guard so all the time on guard retention is wasted. And when someone isn’t trying to pass it’s hard to capitalize on mistakes and to unbalance them.
Old school guard works of the top guy has no bjj.
But in current year when even street fighter know alittle bjj you cannot have a defensive mindset on bottom,
Some of the best guard work if seen in mma wasn’t even really bjj guys. It’s guys like fedor who immmediatky open guard and go all in on attacking arms.
The rules of sambo and Judo make you attack as the fight transition to the ground.
Modern bjj guys do the same.
But keeping closed guard in mma makes zero sense.
This is why I do guard passing maybe 1/10th what most bjj schools do. It’s completely different in a fight.’the onus should be on the guy on bottom to do something, if u can’t get a sub immediately you should be wrestling up, going to half guard, butterfly, or k guard.
As posted above. If you’re gonna pull guard you should be shooting a single or high crutch and pulling hair guard right into “Plan B”or “old school” sweeps.
Even if they fail something will happen, and on bottom you need to embrace them scrabble not try to resist it like Kron did.
