Reports: Rockets, C Steven Adams agree to three-year extension

The Houston Rockets agreed to a three-year, $39 million contract extension with center Steven Adams, per multiple reports. The deal is fully guaranteed.
The veteran big man spent the first seven seasons of his career with the Oklahoma City Thunder, starting 466 games. During that span, he averaged 9.8 points and 7.6 rebounds per game.
After one season with the New Orleans Pelicans, Adams became a mainstay for the Memphis Grizzlies, helping their young core led by Ja Morant and Jaren Jackson Jr. finish second in the Western Conference in back-to-back seasons.
Last season, Adams regularly came off the bench for the first time since his rookie season, but remained a solid contributor for the Rockets, averaging 3.9 points and 5.6 rebounds in only 13.7 minutes per game.
Houston had a breakout season this year, landing in second place in the West with a 52-30 record.
The Rockets were 5.0 points per 100 possessions better with Adams on the floor, per Cleaning the Glass. That placed him in the 79th percentile in the NBA.
The contract extension locks up a long-term quality backup for all-star center Alperen Sengun.
