I remember those three guys. Serious fighters, all from Texas if I remember correctly. Texas fighters back in the day were beasts, all of them. Even the gals, I was a team mate of Linda Denley back in the eighties. Such a great person. And consider this as an athlete -
She was still in high school, when she qualified for the Olympics in five track and field events, but because of her professional winnings on the karate circuit, she was ineligible to compete in the Olympics.
I'm pretty sure all those guys mentioned came from the same lineage - Jhoon Rhee, [Texas in the fifties] down through Allen Steen, then down through Pat Burleson. I know Ray came from them, I remember Ray well. He was a wild man with exceptional technique, both in sport karate and in kick boxing. Here's a nice piece on it all.

I also remember Billye Jackson fighting Benny the Jet in kick boxing back when they were both undefeated. Jackson won, no easy feat to beat the Jet back then. I remember Tim Kirby being both a great fighter and a great Kata man.
