8. Expendable: Dwight Powell
Dwight Powell has been a Dallas Maverick since 2014, as he was moved to Dallas from the Boston Celtics as part of the Rajon Rondo trade. Powell was just a throw-in in that trade but has become the longest-tenured player on the team.
In 10 seasons with Dallas, (not all full seasons, as it includes this season and the year he was traded to the team) Powell averages 7.5 points, 4.5 rebounds, 0.6 steals, and 0.5 blocks per game while shooting an efficient 60 percent from the field.
Powell became one of Luka Doncic's favorite pick-and-roll partners over the years, but he was never in the position to be elite at his role. He has been a starter for the majority of his time in Dallas, and he was never a good enough big man to start, causing fans to turn on him quickly.
He receives more flack from fans than anyone else on the team, yet still gives his all on both ends of the floor and is the perfect teammate. Powell is a great example for his teammates on and off the court, but that doesn't mean he isn't expendable.
Dallas re-signed Powell on a three-year deal this summer, and he could be someone that the Mavs look to trade at the deadline to a team that needs a backup center. Powell is a solid big to bring off the bench to bring energy and hustle, but he isn't someone who should be playing significant minutes on a nightly basis.
