Well, why not? 

IT WAS TRAINING and nothing else.  I grappled him because I wanted to know what he is capable of, and I saw opportunity to learn from it in a training environment. Now I know what a MAA can do, and I take responsibility for MY own training.  I think walking away without a scrape; injury or need for ice, is winning.

Didn’t Soke say “Play with the opponent”?

Didn’t Takamatsu sensei said “What really matters is guts”?

I’ll let you on to a 2000 year old secret-YOU are responsible for your own training. -Not Soke, not me, not Bruce or your Shidoshi.
