Me too. I still reflexively get excited in late December when I realize the World Juniors are coming up, but then the excitement dies down by the time the games come around. It doesn't help that things get rolling with some boring one-sided blowouts.
I think to some extent the vast extent of prospect and draft awareness and information takes away some of the national "ownership" (for lack of a better word) I feel for Canadian players. When I was young and watching the Juniors, it was just about rooting for my team of Canadian players. Now I'm acutely aware of how on Team Canada this guy belongs to the Kings, and that guy belongs to Anaheim, and we were hoping that other guy would fall to the Leafs in the draft but he didn't, etc. I'd actually rather watch Finland than Canada because of it.
