George Karl likes the mission he's accepted. The Nuggets coach is out to prove that you don't need superstars to win big in the NBA. For much of Sunday night, Karl was building a case. Then the old you-need-superstars theory rose up. Rose up big. The amazing tale of Kevin Durant and Russell Westbrook reached its zenith Sunday night as the Thunder bounced Karl's Nuggets 124-118 in overtime. Durant's ascension to basketball royalty? Westbrook's rise to superstardom? Neither could be disputed after one of the wildest games in Oklahoma City's NBA history.
