I'm amazed at the amount of spinning and backpedaling you're doing to try and make Leno look like the innocent just because you like him best.
You'd do the same for Conan, so what's the big deal?
No, I don't think they would. If the situation were reversed -- if Conan had promised Leno The Tonight Show and then joined with NBC to take it back from him, thereby going back on his word -- I'd be condemning Conan just as much as I've been condemning Leno.
This isn't about who I like better as a comedian. I'm a Craig Ferguson sort of fellow anyway. This is about the simple fact that Leno and NBC screwed Conan over and displayed a distinct lack of personal honor and respectability by doing so.
