Make me another one who will be on board if there are the no-gimmick teams involved, but otherwise I won't be paying attention.
For me one of the key aspects of interest I had previously with former best on best national tournaments like the olympics, was the near complete dropping you had of segregation among hockey fans in communities.
Growing up in Canada, while there would always be a dominant NHL team that every area would support. There is always a mix. The family whose parents cheered for an original six 6 team, and it has been passed down generationally. A girl who cheers for Pittsburgh because Lemieux was the most dynamic player when she started to follow the sport as a kid. Or the guy who cheers for the the biggest local rival purely to rebel against other members of his family. Whatever it might be there was almost always some division at schools/pubs/workplaces etc. But a big part of the national supporting experience was always a near complete dropping of any seperation between local hockey fans. When the olympics would come around we would all be on Team Canada, and I loved that.
The inclusion of the young blood team introduces a new side, a new division, a lack of local solidarity. And with that. I lose interest.
