They probably know that their rating will be down if they only show or mainly show Leafs game. They will probably go back to more Leafs game as they get better in the next couple of years, if they get better that is.
I'll be impressed with CBC when they stop showing Leafs games and replace them with nothing but Habs games. No Sens. Just like we had to endure the Leafs. CBC used the excuse that the Leafs were a better team for a few years and the Habs were not so good. Well the Leafs are the lowest of the lows now and the Habs are the toast of the league along with a few other teams, plus all the celebrations this year. Leafs should do not exists on tv unless it's on their own channel.
