He hopped around the court waving his arms with 20 seconds remaining to encourage fans to cheer, but it was way too late for that.
Their voices had been booming inside and outside for hours by then, having waited 50 years to celebrate a winner after Kareem Abdul-Jabbar and Oscar Robertson led the Bucks to the championship in 1971.
In a season played played largely without fans, the Bucks had 65,000 of them packed into the Deer District outside, a wild party that figured to last deep into the Midwestern night.
Confetti rained down inside as fans chanted “Bucks in 6! Bucks in 6!” — what began as a hopeful boast by former player turning out to be a prophetic rallying cry.
The Bucks became the fifth team to win the NBA Finals after trailing 2-0 and the first to do it by winning the next four games since Miami against Dallas in 2006.
Chris Paul scored 26 points to end his first NBA Finals appearance in his 16th season. Devin Booker added 19 points but shot just 8 for 22 and missed all seven 3-pointers after scoring 40 points in each of the last two games.
The teams that came into the NBA together as expansion clubs in 1968 delivered a fine finals, with the last three games all in the balance deep into the fourth quarter.
The Bucks won them largely because of Antetokounmpo, a two-time MVP in the regular season who raised his game even higher in the finals and was voted the NBA Finals MVP.
