The last time Erving Walker played against Kentucky superstar John Wall, Florida’s point guard didn’t know it. There’s no chance of Wall going unnoticed for the second meeting. Walker and the University of Florida (11-4, 0-1 SEC) play host to Wall and the No. 2 Kentucky Wildcats (16-0, 1-0) at 9 p.m. Tuesday at O’Connell Center. Kentucky coach John Calipari is the new kingpin of Southeastern Conference basketball, and his Wildcats are loaded with talented players, a few who chose to play for Kentucky over the Gators.
