ST. LOUIS — About the only thing Kansas and Eastern Kentucky have in common is that they are playing each other in the second round of the NCAA tournament.The Jayhawks are the big, bruising bullies from the Big 12, touting a roster stocked with five-star freshmen, a championship-winning coach and enough March pedigree to stack up with St. Patrick.The Colonels are the scrappy underdogs from the Ohio Valley Conference, whose senior-laden roster would rather shoot 3-pointers than free throws and that relishes the underdog role.The No. 2 seed Jayhawks and 15th-seeded Colonels meet Friday in St. Louis, with the winner getting seventh-seeded New Mexico or 10th-seeded Stanford in the third round.“Being the underdog is always fun,” said the Colonels’ Glenn Cosey, “especially if you can pull off an upset. And a lot of people seem to get with the underdog, so it should be fun.”The fellas from Eastern Kentucky all seem to have their favorite upset memory, too.Eric Stutz, the 6-foot-8 forward with the hippie-style “peace and love” bandanna, grew up in Indiana and watched Butler reach two Final Fours.
