It's the question of the NCAA tournament. Everywhere you turn, people are chanting "Rock Chalk Jayhawk" and nobody really knows what it means. We asked people all weekend, and we got as many answers as people we asked. Some talked about the bounty of limestone in Kansas, others about choo-choo trains and still others about mythical birds. Some even went zen on us . . . one person's response: "It's everything." Another's: "What isn't it?" After Monday night's impressive performance (yes, I know, I was wrong) the answer is easy: It means "winner."
