No disrespect to Roy Harris - he has done very much for the BJJ community. It's just for example me and my teachers completely disagree on his training methods
Also... I would watch his instructionals when suffering from insomnia and be surely cured
Just to point out that his way is not the only way...
BTW... I also heard that Michael Jen, a student of Roy Harris (who IMHO has much better instructionals than Harris) when he used to compete back in the day he yelled after a win by wristlock in competitions "Aikido wins!" everyone else seemed pissed
