Marquee was a stupid idea. It's biting the hands that have fed them for generations. When I was a kid it seemed like the white Sox were more popular. WGN staying on broadcast TV and going national while the white Sox went to pay tv was a huge reason that they became more popular. Large parts of the area didn't get cable. If people wanted baseball, they were going to watch the Cubs.
I'm sure that they could have bought a local channel that is also on cable and they wouldn't have this problem. I'm sure that they are one of those organizations that is driven to touch the hot stove because they're smarter than everybody else, but they would have learned. I'm sure that they're going to use their big brains and let their creativity blossom to just do what everybody else is doing and wonder why they're having all of the same problems as everybody else.
