I think you're underestimating/overestimating the Habs national/regional appearances on HNIC. I would guess 10-6 for national games, think positive.
Remember, no inter-conference play. The only time the Habs will be on a Sportsnet channel this season will be when they play the Senators on Sportsnet East. That game will be on Feb. 25, most of the Sportsnet schedules were released Monday afternoon. All 3 Habs-Jets games will be on http://www.tsn.ca/jets/. No surprise here, all the Habs-Leafs games are nationally televised on HNIC with 1 game on TSN.
