Hot take, but I like the USA's defensive core one through six better than Canada's. Makar is definitely the best of either bunch though.
However, I won't be watching this as I hate NHL-sponsored gimmicks that are money grabs. The 1996 World Cup was one of the best events I ever watched, even though I was still a young lad. It's not hard to bring that supreme tournament back than this rubbish. Don't even do a group stage, just take the top 16 in terms of current IIHF ranking points and do a playoff bracket ranked 1 v 16, 2 v 15, etc. The first and second rounds are single-game eliminations, the third round is best out of three, and the finals are best out of five. Boom, rating galore.
