Good on him!

It's always remarkable to see someone who can be so effectively powerful when the situation call for it yet so cool, calm, collected and able to spar constructively in normal training as well.

That would be one of the marks of someone with a good mentality for the sport in my humble opinion.

Also noticed a brace on his right knee. A past injury perhaps? it doesn't seem to be restricting him in any way now which is a credit to him too really. It takes a lot of work, patience, dedication and the right direction from a good coach to come back to full competition after an injury i think!
