Notably, Butler's jersey displayed the name "Butler III" alongside his No. 10. After the game, he revealed the change was permanent and in honor of his father, who died a year ago to the day.

Curry was the other leader of the Warriors win, recording 34 points on 10-of-19 shooting (8-of-16 from 3-point range), six assists and five rebounds.

Butler joined the Warriors earlier this week on a complicated four-team trade that cost the team Andrew Wiggins, Dennis Schröder, Kyle Anderson, Lindy Waters III and a protected first-round pick. The six-time All-Star left the Heat on somewhat hostile terms, as he received three separate suspensions for a variety of offenses that boiled down to him no longer wanting to play for the team.

The Warriors represented a fresh start for Butler, especially after they gave him a two-year, $121 million extension that will align his tenure with the team alongside Curry's current deal. Golden State now has the oldest core in the league with the the 35-year-old Butler, 36-year-old Curry and 34-year-old Draymond Green, but that isn't as much as a problem when you're trying to win now.

The win improved the Warriors record to 26-26, currently good for 10th place and the final play-in spot in the Western Conference. They'll face a stiffer test on Monday, when they face the Milwaukee Bucks on the road.
