Dakari Johnson pledged to Kentucky Saturday night as Coach John Calipari and the Wildcats took another step toward assembling arguably the greatest recruiting class in the history of college basketball. With the addition of the 6-foot-11 center from Montverde (Fla.) Academy, Kentucky now has the Nos. 3, 5, 6, 12 and 30 players in the 2013 ESPN 100. They remain in the mix for the No. 1, No. 4 and No. 7 players as well in Andrew Wiggins, Julius Randle and Aaron Gordon — all of whom will sign in the spring.
