Victor Wembanyama has another big man to help him out in San Antonio. And the Houston Rockets continued their offseason improvements Monday as the NBA’s free agency period got underway.

The Spurs lured center Luke Kornet away from Boston with a four-year, $41 million deal, a person with knowledge of the agreement told The Associated Press. The person spoke on condition of anonymity because the team cannot announce the deal until the league’s signing moratorium for most contracts is lifted on Sunday.

Kornet was part of Boston’s 2024 NBA title team and has shot 68% from the field in 205 games, mostly off the bench, over the last three regular seasons. He figures to add frontcourt depth to the Spurs, who are hoping to have Wembanyama — the 2023-24 NBA Rookie of the Year and an All-Star this past season — back and ready to go after he was diagnosed with deep vein thrombosis in a shoulder back in February.

The Rockets, meanwhile, added veteran forward Dorian Finney-Smith on a four-year, $53 million deal shortly after free agency opened. ESPN first reported the deal, and a person with knowledge of the agreement confirmed the terms to AP.

Houston becomes Finney-Smith’s fourth team after stints with Dallas, Brooklyn and the Los Angeles Lakers. He’ll be added to a Rockets club that earlier this summer landed Kevin Durant in a blockbuster trade with Phoenix, though that deal cannot receive formal approval from the NBA until next week.

Finney-Smith averaged 8.7 points and was a 41% shooter from 3-point range this past season.

ESPN also reported that the Rockets’ run on free agents continued with the addition of center Clint Capela, who spent the first six years of his career in Houston before playing for the last five seasons in Atlanta. Capela agreed to a three-year deal with the Rockets.

Dallas, which needed some point guard help especially because the newly re-signed Kyrie Irving — rehabbing from an ACL tear — may not be ready to play until about midseason, agreed with D’Angelo Russell on a two-year contract worth nearly $13 million.

Russell would be part of the backcourt depth on a club with an imposing front line that, if healthy, would include No. 1 overall pick Cooper Flagg, 10-time All-Star Anthony Davis and promising young center Dereck Lively II.

The free agency period officially opened at 6 p.m. Eastern time on Monday, but in actuality, was rolling long before that.

LeBron James has already opted in to a $52.6 million deal with the Los Angeles Lakers for this coming season, the Rockets traded for Durant — not a free agency move, obviously — and the Los Angeles Clippers saw James Harden decline his option in return for a new deal and a raise. There was even a surprise addition to free agency, with Portland announcing it has bought out the contract of former No. 1 pick Deandre Ayton — making him able to sign with any team he chooses.
