Jordan was 35 when he won his last title, then he retired, that was pretty much the end of his career

. 3 straight titles however, he returned 3 years later for a crap Wizards team and still played great, averaged 20ppg. note that he didnt play for 3 whole years, returned at the age of 38, and still was among the top scorers in the league. he even scored 40 pts in a game when he was 40 years old. LEGEND
im not saying that Duncan isnt amazing, consistent or a legendary player. but, for me, no-one competes with this beast...
