I don't believe in fairy tales, especially when they are being brought to me by multi-billion dollar corporations such as the NFL, NBA, ESPN/Disney, CBS, etc. And that's what this "Top 10" list basically consists of: Cinderella stories that are far too good to be true. I know. I'm cynical.
While it would be much more difficult to arrange and manipulate an entire season as opposed to a single contest, that doesn't mean it's impossible. Some of the best, most rewarding things in life are the ones you work the hardest to achieve. In the case of professional sports, these particular storylines were too important (read: valuable) to let go of too early.
