How often do you get to roll with your instructor? If you roll often do you think rolling with your coach makes a huge difference? I get to roll with our head black belt probably once every couple of weeks. I don't feel like I really learn anything from it except some humility. I roll with our purple belt instructor at least once a week. He is in charge of the majority of our classes and I think it helps him more than me because it's a good way for him to figure out what we need to work on as a class. I don't take these rolling sessions for granted though and it's great to be able to experience higher levels of bjj.
