To your made up point though, Kareem did just fine from age 30-34. Russells numbers stayed consistent from 30-retirement, Bob Pettit averaged 28 and 15 at 30 and 31, Mo Cheeks had some of his best years after 30, Artis Gilmore was a beast til he was 35, Larry Nance as well. Bernard King averaged 28 a game at age 34....you did say "almost nobody" though.
