ESPN's Jason King summed it up:
Painter said the popularity of the NCAA tournament has lured in scores of "casual" fans. Most don't follow college basketball closely until March and most don't have sports backgrounds. The tournament, Painter said, becomes a "social event," with everyone suddenly becoming an expert after filling out a bracket.
"It's great for the tournament," Painter said. "But from a fan's standpoint, there is a pool of people [who] don't understand the game. They don't understand all that goes into winning and losing and the things that can happen. They just react to how you finish and they judge you on that."
The bottom line is that the tournament is over-emphasized and the rest of the season basically means nothing. The NCAA needs to fix that.
