Duke's Zion Williamson sits on the floor following a injury during the first half of an NCAA college basketball game against North Carolina, in Durham, N.C., Wednesday, Feb. 20, 2019. Duke might have to figure out what the Zion Show will look like without its namesake. All because of a freak injury to arguably the most exciting player in college basketball. As his Nike shoe blew out, Williamson sprained his right knee on the first possession of what became top-ranked Duke's 88-72 loss to No. 8 North Carolina.(AP Photo/Gerry Broome)
