Just watching the preview on Boxing Guru UK...Freddie left to train Mickey Rourke, but, before that, he was right down the road from LA, at a gym in La Habra. That has been a pretty solid gym for some time, producing some decent pro. Among them, if memory serves, were Rocky Garcia and Joe Ruelas.
Back in the day, Roach used to work with whoever walked through the door. I know a couple convicts from that area that he worked with.
