Where they stand now: Considered one of the greatest coaches in American sports history, Popovich's résumé speaks for itself. His job was in danger at one point early on, but there's been no looking back since. Popovich has proven adaptable: His early Spurs teams were defensive-minded, low-post brutes before evolving into drive-and-kick, spread offense dynamos. Along the way, he's preached culture and worldliness in a way rarely seen in sports. The only knock on Popovich is something he himself has always said: Coaches are only as good as their players. The Spurs have finished below-.500 the last three seasons as they enter a long rebuild.
