Had the honor of training with "Coach" Marr at Grappler's Edge in Denver, CO from 1999-2001. Great leader and teacher. He had 2 expectations: (1) get in a good workout and (2) learn something new every training session. The dojo was great. Coach loved training wrestlers because we know how to train HARD, love to train hard, really prefer to work things out on our feet (rather than jumping guard) and for us good go-lives are ridiculously intense. Coach 's stated goal was to change us "knuckle-draggin' neanderthals" (aka folkstyle wrestlers) and turn us into real grapplers (he was a World level Judokan). If you ever have the chance to train with Coach Marr or attend one of his clinics... do it. And if you want a real treat, try a go-live with his son, Nick. Peruvian necktie comin' your way...
