Intresting stuff. Looks like they're all about attacking subs, and give little thought to position at all. Just not as tight or controled as I am use to seeing in grappling.
Looked a bit contrived and slow. Bit rough round the edges but they might be onto something there. Anyone tried it?? I've been taken to the ground during Muay Thai sparring sessions before but it doesn't last long and is usually done by the guys who cross-train; therefore I would say its more MMA than muay thai.
