Interesting, haven't heard that one. Did he say why? Usually breathing through the mouth aids in getting yourself knocked out.
Your body needs oxygen to make that much movement happen. If you don't get the air, you get tired much faster.
The thing that gets you knocked out if having a loose jaw when you get hit and/or being gassed, not intentional heavy breathing.
Though I'm still on the fence as to whether or not he came into this fight injured again and is actually gassing.
