Overview of the Signing

The Boston Celtics have officially signed Ron Harper Jr. to a two-way contract, as reported by ESPN's Shams Charania. This decision follows the team's recent waiver of rookie RJ Luis Jr., which opened a spot for Harper on the roster. Harper, a 25-year-old forward, previously participated in the Celtics' training camp on an Exhibit 10 deal, showcasing his skills and performance during the preseason.

Harper's Background and Performance

Ron Harper Jr. is the son of former NBA player Ron Harper, who won five championships, and the older brother of San Antonio Spurs rookie Dylan Harper. Harper Jr. went undrafted in 2022 after a successful college career at Rutgers University. He has since played for the Toronto Raptors and the Detroit Pistons, accumulating experience in the NBA and G League. Last season, he averaged 15.7 points, 3.8 rebounds, and 2.3 assists in the G League, demonstrating his scoring ability and versatility.

During the Celtics' preseason, Harper Jr. averaged 4.3 points, 1.0 assist, and 0.7 rebounds in limited minutes across three games, shooting 42.9% from three-point range. His performance in training camp and the preseason solidified his position as a strong candidate for the two-way contract, allowing him to contribute to the Celtics' roster depth.

Official Statements & Responses

The Celtics' decision to sign Harper Jr. reflects their confidence in his potential to make an impact this season, especially with the absence of star player Jayson Tatum. Coach Joe Mazzulla praised Harper's professionalism and improvement, noting, "His basketball IQ has really improved. He’s shooting the ball really well."

Criticism & Opposition

While the signing of Harper Jr. has been generally well-received, some analysts question the decision to waive RJ Luis Jr., who was acquired in a trade with the Utah Jazz. Luis had limited opportunities during the preseason, and his release raises concerns about the Celtics' evaluation process for young talent.

What's Next for Harper Jr. and the Celtics

With the signing of Ron Harper Jr., the Celtics now have all three of their two-way slots filled, alongside rookies Amari Williams and Max Shulga. Harper Jr. is expected to split his time between the NBA and G League, where he can gain valuable experience and development. The Celtics will begin their regular season on October 22 against the Philadelphia 76ers, and Harper Jr. may play a role in providing additional depth as the team navigates the challenges of the upcoming season.
