Not a very good BB to lose control are you?

You should have complimented the kid for sweeping you, it obviously worked. Regardless of doing techniques slow how does that help him, it's easy to react to slow things, no matter how advanced they are. The kid is still learning like you, so work at his level, with basics and simple things, not super slow.

The little kid has an excuse to not be able to control his sweeps, he is still young and learning. You don't have any excuse to kick him like that. If you are going to do that make light to no contact, don't knock him out. Who wants to learn from someone who does that to em?
I hope you learned something.........
