What's cool about platforms like Twitter is that you can interact with other people on any subject - even professionals, as was the case today when Patrick O'Sullivan and I disagreed on not just Patrick Roy leaving his dual position as Colorado Avalanche head coach and VP of Hockey Operations, but goalies as coaches in general.
I think Roy saw that GM Joe Sakic wasn't going to provide him with another top-4 defenseman - although some are still available on the free agent market, namely Kris Russell, whereas the Avs also have decent trade chips up front with the likes of Matt Duchene to acquire one from another team, be it one of those who have already moved (Adam Larsson, Erik Gudbranson, Dmitri Kulikov, P.K. Subban, Shea Weber) or someone who is currently under the radar (Torrey Krug, Niklas Hjalmarsson, Alexander Edler or Nathan Beaulieu).
And while a lot of people discredit Roy's Jack Adams Trophy because the team's possession stats have always been skewed, that's more the product of a D that cannot find a way to get the puck to their forwards than of a coach who doesn't understand what system to play or what buttons to push; other former goalies have done (Gerry Cheevers) and are doing wonders behind the bench, such as Jeff Blashill and Peter Skudra, not to mention Jacques Martin's work on the Pittsburgh Penguins' sub-par defense group, enabling them to play to their strengths and hide their weaknesses on their way to this year's Stanley Cup.
And that's saying nothing of the work the likes of Félix Potvin and Jocelyn Thibault are doing in Juniors and the fact that a good portion of NHL in-game analysts have played the position, the best of whom are Marc Denis, Kelly Hrudey, Darren Pang, and Glenn Healy, and José Theodore being one of the worst. That shows a pretty deep understanding of the game...
I, of course, might be tooting my own horn:
