The Boston Celtics have their eyes set on a major upgrade at center, with Ivica Zubac from the Los Angeles Clippers emerging as a prime target. Landing the 7-foot big man could be a game-changer for the defending champions, bolstering their defense and rebounding while providing a reliable pick-and-roll partner. But hold on—recent reports suggest this dream deal might be hanging by a thread, thanks to a little-known NBA rule that’s quietly sabotaging Boston’s trade arsenal.
In a bombshell report from Brett Siegel of ClutchPoints, details emerged about the Celtics’ potential pursuit of Zubac. Sources indicate that the Clippers have shown prior interest in Anfernee Simons, the young guard currently with Boston but previously with the Portland Trail Blazers. Simons is in the final year of his contract, making him an attractive piece for L.A. The proposed framework? Boston could send Simons along with a couple of draft picks in exchange for Zubac. “If the Clippers can get a few draft picks from the Celtics for Zubac, that could be an intriguing scenario for them to discuss,” Siegel revealed.
On paper, it sounds promising. Zubac, a former All-Defensive team selection, is thriving this season with averages of 11.8 points on nearly 60% shooting, 11.6 rebounds (including 3.5 offensive), and 2.6 assists per game. His team-friendly contract—$18.1 million this year, escalating to $21 million in 2027-28—makes him a long-term asset for a contender like Boston. Pairing him with emerging star Neemias Queta, who’s been a revelation as a starter, would give the Celtics one of the league’s top center tandems. Queta’s rim protection is elite, with opponents shooting 9.7% worse at the basket when he’s defending, per databallr.com. His screens and lob threat add vertical spacing that complements Boston’s perimeter-heavy attack.
Moreover, the deal could provide financial relief. Shipping out Simons’ salary might push the Celtics below the first apron or even the luxury tax threshold, freeing up room for future moves. Zubac’s addition would enhance Boston’s rebounding and interior defense without disrupting their second-ranked offensive net rating. Interestingly, both Zubac and Queta aren’t traditional floor-spacers, but Boston’s system has proven adaptable, turning potential mismatches into strengths.
But here’s where the drama unfolds: the trade’s fate could be doomed by the infamous Stepien Rule—the “secret killer clause” that’s leaked as the potential deal-breaker. This NBA regulation prevents teams from trading first-round picks in consecutive years, ensuring franchises don’t mortgage their future recklessly. For the Celtics, this means they can’t offer picks too close together. If Boston dangles their 2026 first-rounder, the next one they could include wouldn’t be available until 2031—a whopping six-year gap. That’s a far cry from the premium packages other rivals might assemble, potentially making Boston’s offer look underwhelming to the Clippers.
Will L.A. bite? The Clippers might not even want to part with Zubac, who’s integral to their lineup. Even if they do—whether in-season or this summer—Boston’s draft capital limitations could leave them outbid. To sweeten the pot, the Celtics might need to offer minimal protections on those picks, similar to how a top-1 protected selection helped them snag Derrick White from the Spurs. But with the trade deadline looming, time is ticking, and this clause could shatter the entire negotiation.
From Boston’s perspective, pursuing Zubac is a no-brainer. It addresses key needs, sheds salary, and positions them for sustained contention. Queta’s growth is exciting, but Zubac is a proven upgrade. Still, it takes two to tango, and if the Clippers balk at the spaced-out picks or find better suitors, this blockbuster could fizzle out before it even starts.
Celtics fans, brace yourselves—this “secret killer clause” might just keep Zubac in Clipper blue for good. Stay tuned as the deadline approaches; one wrong move, and Boston’s championship window could slam shut.
