I just can't agree with this sentiment. The Avs defenseman have been SO bad forever, and the Avs core all have had sub par performances especially last year (EJ had a down year, Barrie wasn't quite the same, Duchene put up a lot of points but only in the second half in an inconsistent year like always, Mack is young but still hasn't taken that next step, Landy had a down year, Varly wasn't the same).
To see all of those players play more like secondary players, and fail to step up and take leading roles, and the dog crap defense they've employed forever, and the goaltending unable to perform superman acts regularly, and isolate the main problem as behind the bench is just doesn't add up IMO.
The main problem I see that Roy contributed to in terms of the players underperforming was taking his partnership mentality too far, and it took until halfway through last season to realize it.
I just can't see how you can objectively assess the performance of the "system" with such a crap defense especially. It's like trying to judge the nautical skills of the Captain of a cruise liner with a giant hole that was left in the underbelly of his ship as he sailed out of port.
Again, the fact the team two years ago played with giant gaps between the O and D and had a disastrous start that doomed them by December before Roy finally started preaching "Puck Support" (his words, not mine) is not just on the players. That's on the coach.
And last year, when the team once again faceplanted to start the year, the team was overemphasizing defensive zone play and shot-blocking, going full matador in the neutral zone before finally realizing that getting out of the defensive zone is really, really hard when you're yielding the other two, is not just on the players. That's on the coach.
Did the players decide to ice a "third line" to start the year of Rendulic-Soderberg-Rantanen? Nope. That was the coach. Did the players decide that Nate Guenin and Nick Holden should be out there on the PK...together? Nope. That was the coach.
And how many times can you watch man-to-man defensive coverage fail before finally realizing there's a reason no one else in the NHL employs that system? Would better players have done it better? Probably, but man, opposing coaches sure had fun tying the Avalanche up in knots in the attacking zone because they knew exactly how to exploit the M2M system.
You seem to be implying that the Avalanche roster is that of an expansion club, and I don't think that's the case. I am every bit as frustrated as you are that this effin' club can't for the life of themselves develop an elite defender, or even a viable stay-at-home guy. But to say they didn't have a very talented puckmover and at least a decent top pairing guy is just plain wrong. And while he was waaaaaay overworked, Beauchemin is still a legit NHL defender.
You can say that Roy wasn't given the right tools, and you'd be right to an extent. But don't tell me that Roy did the best he possibly could with what he had, because he didn't. He continually used bad schemes, made adjustments far, far too slowly, and was absolutely abysmal when it came to in-game adjustments.
I don't expect this club to suddenly vault up Ye Olde Corsi Ladder under a different coach, but for Christ's sake, when you're pretty much dead last when it comes to shots taken and shots given up and your roster still sports some pretty damned good players, that's not all on the players. That's on the coach.
We can also look at your ship analogy the other way: A ship so shiny and invincible that a chubby opera singer who had never so much as jumped in a swimming pool could captain it to the promised land. That shiny ship was the Anaheim Ducks when they had not one, but TWO elite franchise defensemen and some pretty fearsome firepower up front. Am I not allowed to say that team won the Cup in spite of its coach, because that's exactly what happened. To try and definitively say it's the players or it's the coach is near impossible, all we can do is observe, analyze, and extrapolate. And the conclusion I drew is that the Avalanche have a multitude of problems...and the head coach was one of them. It remains to be seen if that particular problem will be solved.
