David Robinson was 37 years old when he retired, his legacy as the greatest player in San Antonio Spurs history firmly intact.
It's been 10 years since Robinson left the team in the hands of Tim Duncan and a couple of young guards named Tony Parker and Manu Ginobili.
Now it's Duncan's legacy that is being debated as the Spurs entered Game 4 of the NBA Finals on Thursday night with a 2-1 series lead over the Miami Heat. Duncan is now 37.
He and Robinson became friends when Duncan was drafted No. 1 overall in 1997. Duncan would tease Robinson about getting old, and now it's the 47-year-old Robinson who sees his younger friend dealing with those same issues.
