Rockets rookie Bruce Thornton looks like the perfect Marcus Smart understudy

Bruce Thornton hasn't needed long to turn heads at summer league. He's been a two-way force of nature, shooting the lights out and defending with impressive range and physicality as he quickly vindicates the Houston Rockets for gambling on him at the 2026 NBA Draft.

Though Thornton was drafted to create depth at point guard with Fred VanVleet coming off of a torn ACL, the signing of Marcus Smart has given him another perfect mentor.

Thornton's summer league success has been predicated on his uncanny ability to impact the game on both ends of the floor. Through four appearances, he's averaging 21.2 points, 3.8 rebounds, 3.8 assists, 3.0 steals, and 2.8 three-point field goals made on .439/.440/.737 shooting.

Rather than leaning on one performance that sways his averages, Thornton has been consistently prolific during summer league action.

Beyond the numbers, Thornton has brought a culture-fitting intensity on defense to balance out the welcome addition of tremendous shooting. Not bad for a second-round pick.

What rounds Thornton's brilliant summer into form is how fearless he's been when defending bigger players. It's almost Smartesque.

Thornton's defensive intensity will likely make or break his minutes under Rockets head coach Ime Udoka. What he's shown during summer league, however, is similar to what Smart has managed to hang his hat on: A refusal to back down when challenged on defense.

That's been evident throughout summer league, but there was no more Smart-like play than when Thornton battled 6'10" Philadelphia 76ers big Johni Broome on both ends of the floor.

That sequence epitomizes the Smart comparison and the reason Thornton should succeed in the NBA. Yes, Thornton stands at 6'0" without shoes, but he has a powerful 223-pound frame and a 6'5" wingspan. Both physical attributes allow him to play bigger than his height.

The reason Smart is the perfect mentor for him is simple: He's had to overcome similar issues related to size and still became one of the premier defenders of his generation.

Smart is obviously taller than Thornton at 6'3", but he has a similarly powerful build at 220 pounds and has made a career out of defending players bigger than him. He's utilized his strength to battle in the post against bigs and his IQ to know exactly how to approach any type or caliber of scorer or playmaker. If he can teach Thornton the same, the Rockets could have a special prospect on their hands.

The Rockets may not play Thornton in a truly identical role to what Smart has played during his career, but this is still a golden opportunity for the rookie to learn from a top-tier veteran.
