The Warriors' post-halftime runs are nearly legendary. Entering The Finals, Golden State had outscored this season's playoff opponents by a total of 130 points in the third quarter.
It looked like that trend would continue on Thursday night. The Warriors jumped out to a seven-point lead less than three minutes after halftime.
Cleveland, however, managed to absorb enough of Golden State's push to stay within striking distance heading into the fourth quarter.
James made his 46th career Finals game his most dominant one yet, finishing with a playoff-best 51 points -- and adding eight rebounds and eight assists, too.
The final minute of Game 1 was a mix of controversy and confusion. With 36.4 seconds remaining and Cleveland leading 104-102, James drew a charge on Kevin Durant -- but the call was reversed after official review.
After the free throws, James and Curry exchanged clutch shots that left Cleveland with possession but trailing 107-106. The Cavs earned a chance to retake the lead when George Hill earned a trip to the free throw line. The first attempt went in.
The second one did not.
Incredibly, Cleveland guard J.R. Smith wound up with the offensive rebound -- and a four-second window in which the Cavs could have broken a 107-107 tie.
Instead, thinking his team was ahead, Smith dribbled out the possession until time expired. Only after the horn sounded and seeing James' desperate pleadings for him to shoot did he realize his error.
In 36 seconds, a reversed call, missed free throw and a possible mental error had turned a potential Cavaliers victory into an overtime opportunity for the Warriors.
Alive and rejuvenated in overtime, the Warriors quickly scored nine unanswered points. The surge proved too much for the Cavaliers to overcome in a 124-114 Golden State win.
That, however, did not stop tempers from flaring late. LeBron James, Stephen Curry and Klay Thompson held a heated discussion in the game's latter stages.
The tipping point came when Cleveland big man Tristan Thompson was ejected for a Flagrant Foul 2 ... and then got into a shoving match with Draymond Green.
The focus now shifts to the space between Games 1 and 2. The Cavs must figure out how to improve upon a game in which James scored 51 points while receiving key contributions from several role players.
As for the Warriors, they are on par with their recent standard of excellence. Golden State has now opened 16 of its last 17 playoff series with a victory. Only two of those series ended in defeat.
Game 2 will tell whether the Warriors are on firm footing to keep that streak -- and their hopes for another NBA title -- alive.
