My problem with the way BJJ is taught

I have never enjoyed the way most instructors teach jiu jitsu. They do one move 3 times with a mid-level of detail and then tell everyone to drill it. The thing is they usually fail to specify when to do the move and when not to do the move which is like 90% of the move. Only 10% of the move involves the what. The rest of the move is the when.

Yesterday in jiu-jitsu class, Robert was teaching how to grab a shallow underhook and use it to pass half-guard. My problem is that he didn’t specify what the other person will be doing. I wish he would have specified it as a game where the bottom person tries their best to frame against the armpit and also control the far leg. Then I wish he would have explained the most logical continuation is for top to spin around and get an armbar with the flared frame. Then I wish he would have explained that bottom will transition to deep half during and go 2 hands on the upper leg to defend the armbar. Then I wish he would have mentioned the back take.

I wish Robert covered like 10 of these sequences during class. However, he only showed the shallow underhook. I guess that is why I need to step up my instructional watching, so the level of instruction matches my attention span. Most instructors only go to a depth of 1. I would have at least hoped they went to a depth of 3.

One other grip I have with BJJ is how much time is spent in finishing moves and not about the meta-game regarding grip control. One thing that I can do to mitigate this is watch more high level black belt rolls.
