So according to you it was all Tremblay's doing. Roy had nothing to do with?
Yet everyone blames Tremblay.
It's Tremblay's fault. Roy was the star of the team. Did he have character/attitude issues? Sure, by all account he was a bit cocky/arrogant and had ego. Very prideful probably. But he's your star - you come in and learn to get the best out of him. You don't go for a confrontation/blow up, that's dumb.
I don't know off hand who Edmonton's coach is - but if he were fired today and replaced by someone else - the first thing that new guy would say is "ok - how do I make it work with McDavid". He wouldn't say "Ok - time to show McDavid whose the boss".
So was Roy difficult? Yep. Was his handling of the situation in that game largely his fault as well as why it escalated? Sure, he got pissed and probably could have handled it better. But it's Trembley's
responsibility to ensure it never gets to that level.
You know your goalie is touchy? Ok - pull him early, don't let him get that way.
You see your goalie clearly unhappy/struggling in that game, even reacting to the crowds? Ok - talk to him, calm him down, take him out, don't escalate shit.
So yeah - it's Tremblay's fault.
