I've been doing cricket batting coaching for District level junior players. I used the same drills with an impact bag with cricket bats - heavy things for you American readers Small biffs to begin with and then let them do Happy Gilmores at the bag to get footwork happening.
What always amazes me is how far a golfers lead foot slay open doing that, even with a step drill vs a standard foot position. Many end up with a light bulb that in their standard set up routine that they need more to keep a better balanced finish.
Needless to say, the cricket coaching fraternity pooh poohs "The Cricket Machine" but I've kids in the State Development team punching above their age weight. Thanks Homer!
If you look very close, there is a "cricket bat" which extends from PP#3 through the sweet spot. It can only make contact with one particular dimple of the golf ball for any given setup position...I wouldn't swing OR chip until I knew which dimple it was.
99.9% of cricket coaches view of the bottom hands roles is a head shakingly amusing. Lots of similarities between high profile golf coaches and cricket coaches. Just too much seems as if without regard to alignments in motion or learning to feel what is really going on. More money in golf coaching though!
