Yeah, I learned a lot sparring against all of the Adamsons. You learn to not leave yourself open very quickly. It amazes me when I watch MMA and compare it to watching high level black belts. MMA seems very sloppy to me and I feel that someone like Herb Johnson or Doug Adamson would likely school most of those guys very quickly.
Oh yes, the Adamson's would definitely school most of those guys quickly. I studied under the Adamson's for four years, Ryan Adamson was a really good spar. To the video in OP, WTH is that? No fluidity, no balance, improper posture, poor stance, utter lack of parrying or blocking, crappy footwork and somehow resembles drunken square dancing.
