But there is no "control group" to measure this against. Are playoff games hard to sell because the weather is cold, or because they aren't known about until a week or two before the game, or because the prices go up, or some other factors? We have no way of knowing if playoff games in October would be an easier sell.

Playing in November has never been considered a problem in the past, and the calls for an earlier schedule on fan boards have been pretty few and far between in the 20 years I've been monitoring them. I don't get why Ambrosie is pushing this as hard as he is -- I have to assume he expects a fairly large financial incentive to do it (i.e. a lot more TV money from U.S.) because otherwise it seems like a needless change. If the league does this and Leafs make a deep playoff run (which has decent chance of happening in the coming seasons), Argos will be damaged. And if Blue Jays make another deep October run (which seems much less likely), same thing.
