Well, might as well go sport by sport:
Alpine Skiing: It wasn't Guay and it wasn't Gagnon, but finally Canada has another medal in Alpine after a ridiculous amount of close calls. Women's tech team is promising.
Biathlon: no medals, but still some great performances. Very unlucky in the men's pursuit, too. I'm pretty confident someone will step in to fill J.P.'s shoes.
Bobsleigh: full marks to Humphries for driving out of her mind, but very disappointing showing by the men's team. A medal was always going to be tough but we weren't even close. Still, Spring, Kripps and Humphries should still be there in four years.
Cross-country skiing: disastrous. Not so much that they didn't win any medals, that was always going to be tough, but the entire team just didn't show up. There will be a lot of turnover, and considering how much the women's team has suffered from that I am not too optimistic for the future. Harvey and Valjas are still young and they will probably have to carry the team over the next four years.
Curling: full marks, an embarrassing amount of talented teams are waiting in the wings.
Figure Skating: Chan let a chance for gold get away from him, but apart from that the team did about as well as it could. Always a sport with a lot of turnover so its really hard to predict how strong the team will be in four years.
Freestyle Skiing: Full marks. Two teenagers on the women's side won gold medals and there is a lot of young talent beyond that.
Hockey: Full marks once again. Pyeongchang will be tough on the men's side if the NHL doesn't go.
Luge: Best performance ever for Canada, but three fourth places are tough to take. If the entire team carries on its hard to imagine there won't be medals in Korea.
Nordic Combined: nope.
Short Track: Very disappointing performance, and the entire team on the men's side (apart from Charle Cournoyer) could very well retire before the next Olympics. Still, there is a lot of talent waiting in the wings, its just that people of the calibre of Charles Hamelin are darn hard to find. At the end of the day the disappointing medal haul had more to do with bad luck than with lack of talent, though.
Skeleton: worse performance ever for Canada on both the men's and women's side. Program needs to rebuild.
Ski Jumping: lots of improvements for Canada since 2010 on the men's side and fairly decent results from the women. The team has the potential to stay competitive on the women's side if the proper investments are made.
Snowboarding: fairly disappointing, especially in men's slopestyle. Maltais' silver is nice. Maltais, Ricker and Calve will probably all retire and those will be big shoes to fill. Hard to predict who will be competitive in slopestyle in four years.
Speed skating: the team has been a disaster all year, so wining two medals is a nice surprise. The men's side has a lot of promising sprinters but I'm not quite as confident for the women. Definitively some rebuilding to be done.
Overall good Olympics for Canada, could have gone a bit better. Will be tough to match in Pyeongchang.
