Flyers aren’t competing anytime soon, so I would take a chance on a coach that is great at developing young players. If he fails, the Flyers still suck anyway. Personally I think X’s and O’s Coaches are overrated in hockey. It’s more fluid than other sports, so great players will make things happen regardless. We all know it’s gonna be Torts though
X's and O's in hockey are tricky, because no one is finding new ways to play the game. You have a handful of options, but the nature of the game and actions of your opponent end up melting them down to relatively basic concepts: You're either doing things that are aggressive or protective, in a handful of different flavors. You can't reinvent the hockey wheel, so to speak, it isn't like football where you can come up with innovative schemes or alter the pace of play dramatically or whatever. Like 99% of on-ice decisions are right in every system or wrong in every system.
Hockey is almost more about archetypes than systems. You're a low-event conservative team, you're a fast-flyin' offensive transition team, you're an offensive zone possession team/, you're PP-reliant, etc. What does matter is accountability and buy-in. If you're going to be a heavy forecheck team, then you've got to have every forward committing and cycling their pressure correctly on every shift...that sort of thing.
So you've got to figure out who you are and build the roster accordingly, and then find a coach who can enforce that ethos ruthlessly. Meaning there needs to be a cohesive vision from the top down that impacts the coach you hire and the players you fill the roster with. The Flyers tried to do that backwards with Vigneault—acquire a coach and rip up the team based on what he wanted—and ended up ass-awful.
Looking at what they have, it's hard to figure out what type of team you can build. Their players don't really fit into any consolidated buckets. Not a ton of high-skill guys. Not a ton of defensive savvy. No stalwart defenders or flashy transition guys. Certainly not a ton of speed. Their "youth movement" is a bunch of hard-working middle-6 wingers. Their defense is a shitshow.
Since the players are the ones who...play, you almost need a handful of guys to emerge to show you where you can go with things. Building blocks for the rest of the roster, guys who you know can be effective-to-dominant impact players if they have the right linemates and are allowed to play the game they're best at.
Basically, it all comes down from the President/GM to start molding the roster into something cohesive, so they're f***ed and they'll hire some idiot who also has no idea what to do with this jumble of NHLish Guys.
