10. San Antonio Spurs – 2004
Tim Duncan and the Spurs had an intense rivalry with the Lakers in the 2000s. It felt like they played each other every season because of the magnitude of their clashes. San Antonio had a stronger regular-season record than the Lakers in 2004.

Unsurprisingly, the oddsmakers considered them to be strong favorites. But the Lakers belied their underdog status when they upset the odds and knocked the Spurs out of contention. Derek Fisher scored the all-important Game Five winning points (via Bleacher Report).
