Boston Celtics veteran guard Marcus Smart officially left the franchise on Friday when the Houston Rockets announced his signing. The 32‑year‑old, a former Defensive Player of the Year, will join a Rockets roster looking to add grit after a disappointing 2025‑26 campaign.

What happened?

The Rockets posted on X, “OFFICIAL: The Houston Rockets today announced they have signed free agent guard Marcus Smart. Everyone welcome Marcus to H‑Town 🤘.” Smart’s last season was split between the Los Angeles Lakers, where he posted 9.3 points, 2.8 rebounds, 3.0 assists and 1.4 steals in 62 games while shooting 39.5% from the field and 33.1% from three‑point range. His move ends a nine‑year run that began when Boston selected him sixth overall in the 2014 NBA Draft.

Why it matters for Boston Celtics

Smart’s departure leaves a void in Boston’s defensive rotation. He helped the Celtics reach the Eastern Conference finals five times and the 2022 NBA Finals, logging 108 playoff games for the club. Over his career he averaged 10.5 points, 3.4 rebounds, 4.4 assists and 1.6 steals while shooting 38.9% overall and 32.4% from deep in 697 games. Boston’s recent form has been bleak – the team dropped its last five games (0W‑0D‑5L) and fell 100‑109 to the Philadelphia 76ers on May 2, 2026. Losing Smart’s veteran leadership and perimeter defense could exacerbate those struggles as the Celtics look to rebuild.

How will Houston use Smart?

Houston expects Smart to anchor its backcourt with hustle and defensive intensity. The Rockets have been thin on perimeter defenders, and Smart’s ability to guard multiple positions fits their need for a lockdown guard. His experience in high‑stakes playoff series should help a young roster that struggled to close games last season. Expect him to see heavy minutes in the first half, often tasked with guarding the opponent’s primary ball‑handler.

What’s the fan reaction?

Social media lit up after the news. @YoItsKenneth joked, “Bro better hoop like he did against us in the playoffs,” while @sophie_lane_i noted, “defensive grit for a team that can’t shoot – interesting bet.” Others, like @Stunna999_, reminded fans of Smart’s relentless effort against Kevin Durant in past matchups. The buzz underscores how Smart’s reputation for tenacity still resonates across the league.

What’s next for Boston?

With Smart gone, the Celtics must decide whether to chase another defensive specialist or lean on emerging guards like Payton Pritchard and Derrick White. The front office faces a deadline to fill the roster spot before free agency heats up. Meanwhile, the Rockets will integrate Smart into their pick‑and‑roll sets, hoping his veteran savvy translates into more wins in a conference that remains fiercely competitive.
