Boston Celtics
The rivalry between the Boston Celtics and Golden State Warriors is a new rivalry that began in the 2021-2022 NBA season. They met in the Finals that season, which the last time that happened was in 1964, where the Celtics won in 5 games. This time though, the Warriors completely cooked the Celtics and Stephen Curry took home the NBA Finals Most Valuable Player Award and became the father of the Boston Celtics. In their most recent matchup, the Warriors dominated in their Finals rematch, and Stephen Curry secured those adoption papers.
