There’s nothing more exciting in sports than seeing an elite team get upset by a plucky underdog, and that doesn’t ring any truer than in the NBA, where a playoff upset is legitimately extremely difficult to come by.
From Dirk Nowitzki’s No. 1 seed Dallas Mavericks losing to the No. 8 seed We Believe Golden State Warriors to Alonzo Mourning, Tim Hardaway and the Miami Heat – No. 1 seeds in their own right – losing to the New York Knicks, another No. 8 seed, in Round 1, the NBA has seen some crazy upsets in its playoff history.
Below, check out the biggest ones.
