You need to get your facts straight. Hakeem had a lot of injuries, miles, knee injuries, and heart irregularities by the time he was 37.
If you think Duncan will be as effective at age 37 as he is now, you are absolutely on crack. Even if his game relies less on athleticism, the wear and tear of 15-18 yrs in the NBA gets to all 7 footers and they slow down. Look at Shaq of today. Look at DRob at age 35.
Hakeem didnt show up "for one year". He torched every Center he faced in the playoff, Shaq included. He dominated his peers in the playoffs to a degree that Duncan has never done. Duncan struggled in the playoffs against the stud bigmen he faced in Shaq and Malone, even when Malone was freakin 40 yrs old, going 2-4 in those playoff series. Those are facts.
It was Hakeem who lost 4/5th of his starting lineup after the 1986 season. This is a situation Duncan never faced. Duncan came into the right situation alongside DRob and since then has been complemented by more talent than Olajuwon had alongside him the majority of his career.
You got me on Scottie's stats. Those are so awesome! I mean a guy who scored 14 ppg, WOW!
