#3 DeMarre Carroll
DeMarre Carroll has been in the NBA for 11 years now and played meaningful roles for several franchises during his career. However, the last few seasons have seen Carroll feature in a reduced role. He was picked up by the Houston Rockets in late February after being waved by the San Antonio Spurs.
Unfortunately for Carroll, he wasn't able to make enough of an impact in the 17 minutes of game time he averaged for the Rockets, averaging 6 points on 43.2% shooting. Out of a contract, Carroll is unlikely to be re-signed by the team.
#4 Tyson Chandler
Tyson Chandler signed with the Houston Rockets in free agency at the beginning of the 2019-20 season. He played a few meaningful minutes at the start of the season for the franchise but those dried up once the Rockets went small.
Chandler only managed 1.3 points and 2.5 rebounds per game during the regular season for the Houston Rockets. His involvement in the playoffs was merely limited to two free throw attempts against OKC Thunder, both of which he missed. He'll also be parting ways with the Houston Rockets in free agency.
#5 Russell Westbrook
If the Houston Rockets want to make meaningful changes to their roster, they will probably have to consider NBA trade options for Russell Westbrook.
The former MVP averaged 27.2 points, 7 assists, and 7.9 rebounds per game last season so he certainly has a lot of value. However, his knack for absolutely exploding in the playoffs cannot be ignored either. He simply couldn't get it done along with James Harden when it mattered the most.
The Houston Rockets tried their luck with this duo but it didn't really work out. Trading Harden is not an option while Eric Gordon's contract is too difficult to move. As such, the Rockets are better off trying to trade Russell Westbrook in return for another superstar or multiple role players.
