[quote name="MassHavoc"]I mean this as a serious question: Why wouldn't the players vote to raise the cap?[/quote]
As I remember it -- and it's been a few years since I've spent much time reviewing the CBA, so take this with a grain of salt -- once league revenues exceed a certain amount, the players can vote to add a 5% growth assumption into the cap calculation for the following season. I think the downside to doing that is the risk that league revenues do not grow as hoped and the players, whose salaries are ultimately tied to revenues, end up losing part of their salary. Something like that.
