You can't see that in football, too many teams are evenly matched these days, even in college. Work in basketball shows. A Southwest Missouri State isn't going to a bowl game. It can go to the NCAA's. But a lot of the kids at the tourney get to be seen by national audiences, at least for a day or two.
Any game can turn from a blowout to a nailbiter all the way down.
There has never been a bad tournament. Some bad games, but some real kick ass winners. Because it is so much a part of the worklife of the country as well as the Internet. Because the tourney is fun. It became part of my consciousness in college, where I came across the office pool.
