AARON McKIE walked the floor at the Liacouras Center on Temple's campus about 90 minutes before a game recently and helped direct the team through pregame warmups. The 44-year-old has the same athletic body that carried him through three years under coach John Chaney with the Owls and 13 more seasons in the NBA, including the magical Finals run with the 76ers in 2001. He strides across the floor on the campus where he was a king back in the early 1990s and softly instructs players through their pregame routines. McKie's is a quiet voice, but one that demands respect.
