How can you not be excited about this setup?
There is no way a Slovakia, Switzerland, Latvia, etc teams will come close to medals on their own, so it makes complete sense to mash them up together.
As for the young guys team, I think that team can be crazy good, with shotty goaltending.
I threw together a young stars team, just to see what it would roughly look like.
