Russell Westbrook isn't the only member of the Houston Rockets reportedly dissatisfied with his current situation.

Veteran forward P.J. Tucker has been upset about his contract situation throughout this past season, sources told The Athletic's Kelly Iko, Sam Amick, and Shams Charania.

Tucker has reportedly watched other 3-and-D wings cash in while playing smaller roles for less prominent squads and believes his significance to a contending team merits a raise.

The 35-year-old Texas product spoke openly about a long-term extension prior to the 2019-20 campaign, but he and the Rockets failed to reach an agreement.

Tucker will make $7.9 million in 2021-22, the final season of a four-year, $31.8-million contract he signed in 2017. The 2006 second-round pick was reportedly offended by Houston's decision to delay extension discussions and wait until after February's trade deadline to guarantee his 2020-21 salary.

Tucker has often played at the 5 in the Rockets' small-ball lineups and remains a reliable outside threat, hitting an NBA-leading 90 triples from the corner last season. He averaged 6.9 points, 6.6 boards, and 1.1 steals across 72 appearances in 2019-20.
