CHALK IT UP TO IGNORANCE
I've been filling out NCAA tournament brackets for at least the last 15 years, and I've never heard the term "chalk" used in reference to picking the higher seed. Now it's all over the place, especially at ESPN's DailyQuickie
Does anyone know where this came from? Does it have anything to do with KU's equally mystifying "Rock, Chalk, Jayhawk" cheer?
Help me out here.
