“Choc your feet” seems to contradict Graham Henry’s tracking and tackling video, where he advocates “keeping your feet alive”.

Theres always more than one way to do things I guess.

I think he means shorten your steps so they are “choppy”. Just looks like that because he is standing still trying not to kill the little guys. It’s tough to talk your way through a demonstration… thinking and talking at the same time has never been the strength of the forwards.

Excellent. Substantial length, broad coverage (tackle, post-tackle, breakdown), logical organization, clear statement of principles, very effective demonstrations. And yes, he says chop your feet, not chock them. Well done. Very helpful video.
