Confirming on Peter Martell and Kevin Taylor. Kevin Taylor is black under Renzo, and has a red stripe. Kevin Taylor is, along with Wrestling coach Corey Robinson, the best instructor I have ever trained under. I trained at Titans before coming to Kuwait for the summer (at GB Kuwait under a brown under Drac named Ahmed Alhouli now).
I went to BJJ at Titans between wrestling seasons in High school, and I'll never forget the way, if he watched you struggle or make a mistake, he would work with you throughout the move until you finished correctly. Yelling the whole time as if he was frustrated with something internal about the move rather than you!
Peter Martell is a physical beast, and a black belt under Renzo, a terrifying combination.
