Canada doesn't and shouldn't need Crosby to win. There was a lack of presence in front of the net because some old guys and grinders were added on to the roster where there were clearly better options, but those old guys "deserved the chance for gold" which was taken completely for granted. They had to hang on by their fingernails to get through the quarter and semi finals.
Binnington is erratic in net, but it's not like Canada has better. The USA goalie pipeline has increased dramatically. So has their pool of star players. It's not 2010 anymore.
One wonders what Toronto-born Zach Hyman could have done if he were there, but no sense on dwelling on that now.
The USA is seriously taking over hockey. I wouldn't be surprised in a future where more than half of NHL players are born in the USA. They are at about 30% now to Canada's dwindling 45%.
Hockey Canada is notorious for being an old boys club. They stayed loyal to guys like Drew Doughty, who although is a future hall of famer and member of the 4 Nations winning team, is past his best before date. And as long as guys like Marchand were healthy enough, they weren't going to leave him off the roster completely. Unfortunately he wasn't much of a factor.
Celebrini and Bedard are two of Canada's brightest young stars, and it would've been tough to not take at least one but they were probably hesitant to do so. Celebrini being one of the league's top point getters so far this season made it impossible to not take him. And Bedard's injury where he missed a few weeks gave them a convenient reason to not consider him that seriously.
Canada's goalie depth is terribly weak. Binnington is only here for his past achievements, and has had a poor season with St. Louis. Although I would say that the loss wasn't completely on him. I think all the missed shots, that notably poor 5 on 3 power play execution by Canada, Hellebuyck's big saves, and Americans being ultimately more clutch, were the difference makers. With that said, Canada has definitely declined in the goalies we develop. Gone are the days where we had to luxury of relying on the likes of Patrick Roy, Brodeur, Luongo, Fleury, Price etc. Logan Thompson has been quite good this season for Washington but doesn't have the confidence of the coaches to start ahead of Binner. And he doesn't have the career resume of the Canadian goalies of yesteryears. Whereas the Americans are stacked now in this department.
I think the US has also taken significant leaps in defencemen. Makar and Quinn Hughes are probably pretty even for best D-man in the league, but behind that I think the US now has the edge. Werenski, McAvoy, Sanderson, and Faber are complete defencemen and often an upgrade over their Canadian counterpart. They also had the luxury of leaving guys like Adam Fox and Lane Hutson off the team as they were deemed redundant. While frankly Canada has a lot of D-men that are kind of "mid", like Parayko, Sanheim, Harley. And even guys like Shea Theodore and Devon Toews who have some winning pedigree with their club teams, aren't that special.
I'm not sure if Hyman would've been one of the more immediate players in consideration. Canada will always have the problem of selecting the the right group to put together on a roster. Some like Mark Scheifele, Evan Bouchard have been consistently shunned. And others like Bedard, Wyatt Johnston, Schaefer, Konecny, Chychrun, Batherson were on the outside looking in this time around, but may be options in the future especially for Bedard, Schaefer and Johnston. But the same can be said about the Americans, they could've had the likes of Jason Robertson, Caufield, Hutson, Zegras, Knies, etc.
The US has definitely taken hockey seriously within the past decade or so. Playing in the NCAA system is arguably seen as a better development route than the CHL now. As shown with Canadian kids like Celebrini, Fantilli, McKenna, etc. choosing to hone their craft there. Canada still produces a lot of raw talent and the players show up on the drafts every year, but we have trouble with having them prepare for the pros. Whereas the Americans are better preparing their youth to be NHL ready. From around 2020 onwards, quite a few top draft picks like Lafreniere, Byfield, Owen Power, Shane Wright have turned out to be pretty mediocre in the NHL. While some Americans who were drafted lower turned out to be better pros.
