Brandon said on 550 earlier in the week, that during the 90s, December games sold out 63% of the time. During the 2000s, they sold out 67% of the time.
so when the team was good, December games still were not selling out. In fact, the big comeback game against Houston (playoffs no less) was not even close to a sellout.
so while people can blame the team being lousy, history indicates this is not true. its really the weather.
