Chris Boucher joined the exclusive list of NBA players with back-to-back championships under different franchises in 2019. The Toronto Raptors power forward signed a 2-way contract with the Warriors in 2018 and featured in a single game for the Warriors.

He recorded a 3-point attempt and a rebound, although he was unable to play in the playoffs due to his contract, but was part of the team as they swept the Cleveland Cavaliers in the 2018 NBA Finals.

Boucher signed a 2-way contract with the Toronto Raptors as a free agent on July 20, 2018, and was given a standard contract on February 10, 2019. The Raptors made it to the NBA Finals and went head-to-head with the Warriors defeating them to become the 2019 NBA champions.

Patrick McCaw was selected by the Milwaukee Bucks as the 38th overall pick in the 2016 NBA draft and was traded to the Warriors on draft night. McCaw has three championship rings, which he won in his first three seasons in the NBA, two titles with the Warriors and the last with the Raptors.

The former Toronto Raptors man, who was waived by the franchise in 2021, joined a select team of stars with back-to-back championships under two different teams in the 2019 finals. Although he has limited playing time for most of his Finals appearances, it is as much his win as it is anyone else's.

McCaw has featured in the playoffs in three seasons and won the title in all three (2016-2019), averaging 2.2 points, 1.2 rebounds and 0.6 assists in 7.7 minutes played per game.

#5. Danny Green

Danny Green #14 of the Philadelphia 76ers shoots the ball in front of the Miami Heat bench in overtime at the Wells Fargo Center on January 12, 2021 in Philadelphia, Pennsylvania. The 76ers defeated the Heat 137-134.

Cleveland Cavaliers No. 46 overall pick in the 2009 NBA draft, Danny Green is the final name on the list to have won back-to-back championships with two different teams. He spent a season with the Cavaliers before being traded to the San Antonio Spurs, where he clinched his first NBA championship ring.

The 76ers small forward played a major role in his three championship wins, albeit never winning the Finals MVP award. He is fourth on the all-time list for career 3-point percentage in the NBA Finals, with a successful percentage of 42%.

During his championship win against the Raptors in 2019, he formed a successful partnership with Kyle Lowry and Kawhi Leonard, helping to shackle an injury-ridden Warriors team. Green then went on to win back-to-back championships with the Lebron James-led LA Lakers after leaving the Raptors that season.
