All lists and rankings have an element of this but let's face it, nearly every golf teacher in the world would love to have a ranking on the list to add to their marketing. I've followed Erika for a few years on Instagram and it is pretty clear that she is a good instructor. Her latest stuff reminds me a little of Manuel de la Torre, or George Knudson, and several others who have tried to find a teaching method that removes the paralysis of swing positions. Kind of a 'let the club swing and get out of it's way' approach.
