I've always thought it'd be cool if they gave every Canadian city a home game that day, and just split the network east/west (most people have timeshifting anyway, so they can watch whichever game they want. As an example:
1:00: Buffalo-Ottawa / Minnesota-Winnipeg
4:00: Boston-Montreal / San Jose-Calgary
7:00: Detroit-Toronto / Los Angeles-Edmonton
(I just picked random teams for Calgary and Edmonton to play, since I really don't know who their non-Canadian rivals are)
The downside to this is that you'd either need seven broadcast crews, or you'd have crews calling one game live and then another one while watching a monitor.
If they drop ANY team on HDIC it flies in the face of everything it is supposed to be. Is there enough time in the day to actually have 4 games not overlap? Id bet we get a noon game against an American team.
Noon: Ottawa v Buffalo (maybe Detroit, but Id bet Buffalo. Thats about as Canadian as an American team can be)
3pm: Toronto v Montreal (no brainer)
7pm: Winnipeg v Vancouver (the shiny new team and the potential reigning champs in primetime)
10pm: Calgary v Edmonton (leftovers)
After the shiny newness of the Peg wears off, I think our days as the redheaded Canadian team are done though.
