Yeah, I'm definitely a fan of him. I never noticed that issue, but most of the people I trained with when we would do 'mma' sparring were judoka, who didn't do many leg takedowns, and not a whole lot of leg kicks. So that might be why.Mervin Cook, excellent boxing coach.
The thing about boxing form/structure is its designed for boxing where elbow, knee, and kick attacks aren’t a concern. A lot of the foot positioning exposes the legs for kick attacks or leg takedowns.
