One of my favorite NBA lists …
Dolph Schayes
Hal Greer
John Havlicek
Kobe Bryant
Tim Duncan
Paul Pierce
Dirk Nowitzki
That's the 15-Year Club — the only seven NBA players who spent their entire careers with the same franchise, played at least 15 seasons AND won at least one title. You don't just stumble onto that list — all seven are Hall of Famers, with 21 rings among them. Think about what the list means: excellence, durability, longevity, loyalty, championships … it's your best-case scenario for a basketball career, basically.
