The Boston Celtics just pulled a move that’s got championship pedigree written all over it. They’ve signed Ron Harper Jr. to a two-way contract, and honestly, it feels like they’re collecting infinity stones at this point. When you are a year removed from a title run, why not add some more winning DNA to the mix?
The Boston Celtics are signing Ron Harper Jr. to a two-way NBA contract, agent Drew Gross of WME Basketball tells ESPN. Harper earns Celtics roster spot and enters a fourth NBA season after having strong preseason.

Let’s be real here – this isn’t your typical G League call-up story. Harper Jr. comes from basketball royalty. His old man, Ron Harper, collected five NBA championship rings like they were Pokémon cards, winning titles with both the Chicago Bulls and Los Angeles Lakers. That is the kind of championship experience money can’t buy, but apparently, it can be inherited.
The 25-year-old forward has been grinding it out, and frankly, it’s about time someone gave him a real shot. After going undrafted in 2022 (which still makes zero sense), he’s bounced around from Toronto to Detroit, playing just 11 NBA games total. But here’s the kicker – those numbers don’t tell the whole story.
While Harper Jr. was putting up modest NBA numbers (2.2 points, 1.3 rebounds), he was absolutely torching the G League. Last season alone, he dropped 18.2 points per game while shooting a scorching 39% from beyond the arc. Those aren’t just stats – they’re a statement.
The kid spent last training camp in Boston and clearly left an impression. In four games with the Maine Celtics, he was nearly unstoppable, averaging 22.8 points on ridiculous 50/43/75 shooting splits. Brad Stevens and company were obviously paying attention.
Boston’s championship window is wide open, and depth matters in title runs. Harper Jr. brings something you can’t teach – that championship mentality. Growing up watching his father dominate alongside Michael Jordan probably didn’t hurt either. Plus, at 6-foot-6, he’s got the size to contribute at multiple positions.
The timing couldn’t be better either. With the regular season grinding on, having a versatile wing who can score and defend gives Head Coach Joe Mazzulla another chess piece to work with. And let’s not forget – this is the same organization that turned random pickups into contributors during their 2024 championship run.
This signing feels different, though. There is something poetic about a champion’s son joining the defending champions. Harper Jr. has dealt with his share of adversity, including a shoulder injury that derailed his development for nearly two years. But adversity builds character, and character wins championships.
The Celtics aren’t just signing a player – they’re investing in potential that’s been simmering for years. Sometimes the best stories come from the most unexpected places, and Harper Jr.’s journey from undrafted free agent to Celtics contract is exactly the type of underdog story Boston fans love.
