Saint Louis' analogy comparing coaching to dentistry cleverly implies that Babcock's time as a coach has passed. Instead of old equipment, it is old philosophy and culture that seems to be the problem with Babcock.
Saint Louis has a lot of credibility here. Not only is he an NHL head coach, but he is one that has proven to be effective in getting the most out of his younger players, something Babcock has had difficulty with. Most notably, Cole Caufield, who had struggled under Dominique Ducharme, was suddenly back to his peak form as soon as Saint Louis was brought in.
