I have seen this posted on a couple sites, and the replies are always predictable. The hate is strong.
My perspective: Anderson and Lyoto obviously find some value in working with Seagal. It is puzzling that so many are completely dismissive, when 2 world class fighters are not. The theories I have read on the reasons they are with him, borders foil beanie land.
Aikidoka have really good tai and ashi sabaki, it is worth picking some of it up IMO. Some of them strongly believe in using copious amounts of atemi too; which I can find no fault with either.
