On Oct. 5, 2004, the day Luol Deng officially began his Bulls tenure with double practice sessions under coach Scott Skiles, Scottie Pippen retired from his Hall of Fame career in a low-key ceremony at the Berto Center. Pippen didn't completely disappear. He hung around that training camp and made occasional appearances that season, even drilling Deng, then a gangly 19-year-old with just one season at Duke, in workouts that produced as much substance as sweat.
