The boos echoed from the circle of children gathered in the middle of the Missouri football practice field. Moments later, a laughing Jeremy Maclin emerged from the pack with a smiling child. The kid wore blue Kansas shorts. The KU logo on his left leg had very recently been covered by pieces of tape. Maclin, the former MU receiver and current Philadelphia Eagles star, handed the child a pair of Missouri shorts, ushered him into the Mizzou Atheltics Training Complex and yelled toward a group of onlooking parents, "Boy needs to change shorts!"
