The eminent Tim Finchem announced last week that the PGA Tour "could lose a couple more events" in the coming years. Obviously, this news isn't a proclamation of imminent disaster, or an LPGA-esqe "we may not even have a Tour next year" scenario. As the PGA Tour isn't a publicly traded corporation, it isn't obligated to continually grow in order to return profits to its shareholders. My point here is that downsizing, and potentially losing money in the process, ought not to be a terrible prospect.
The Tour has to pause while assessing the present difficulty in order to take a look further into the future when real trouble will come.
