Advanced stats collectively amount to a proxy for results, i.e. points. Let's talk points, because that's the only metric that really matters.
For the sake of argument, let's assume the Sabres would finish the 2018/2019 season with 85 points with an average NHL coach behind the bench. (I think that's a reasonable number, given last year's result and the undeniable improvement in the team, but the number is somewhat arbitrary.) How many points would they accumulate by employing:
- The best NHL coach imaginable, let's say prime Scotty Bowman for example, but substitute your own choice.
- Phil Housley.
- The worst NHL coach imaginable, let's say Willie Desjardins to use a current example, but, again, substitute your own choice.
What I'm trying to get at here is where Phil falls on the spectrum of coaching competence, and the maximum opportunity cost the Sabres incur by not employing the best coach possible.
