I personally won't miss the TSN games, because of 2 things. I could assemble a team of beer drinking, non-hockey playing buddies for the first game against Toronto and sure as hell we would take them to overtime to delay the Flames broadcast. Seemed like every time it would happen!
That plus it's harder to get through an entire game on the TV without someone wanting to watch something else so I prefer to watch on GC as national broadcasts are blacked out.
