The Milwaukee Bucks are the 2021 NBA Champions, and it's all thanks to Giannis Antetokounmpo's incredibly monster performance in Game 6 of the Finals.

Giannis finished the game with 50 points and 14 rebounds, even scoring 20 in the third quarter to get the Bucks back in the contest after a horrible second quarter showing. Sure enough, his remarkable display got the attention of NBA players who were tuned in for the crucial showdown.

Memphis Grizzlies guard Ja Morant and Utah Jazz teammates Donovan Mitchell and Jordan Clarkson couldn't believe what they just witnessed. Simply put, Giannis became greatness personified when the Bucks needed him the most.

Los Angeles Lakers star LeBron James was also tuned in throughout the contest, even reacting to the Greek Freak's performance early on.

After Milwaukee's 105-98 win, LeBron took to Twitter again to congratulate the Bucks forward and show his admiration for a job well done.

Brooklyn Nets star Kevin Durant also took to Twitter to cheer for the city of Milwaukee. To recall, it was the Bucks who eliminated KD and his Nets in the second round of the Eastern Conference playoffs.
