6. Expendable: Josh Green
The Dallas Mavericks selected Josh Green in the first round of the 2020 NBA Draft, and he improved every year since being in the league until this year. After showing considerable improvement from season to season in his first three seasons, Green has regressed during his fourth season.
Rather than taking the fourth-year jump that many fans anticipated after he signed his three-year, $41 million extension, Green's game has not improved. This season for the Mavs, Green is averaging 6.9 points, 2.9 rebounds, 2.4 assists, and 0.9 steals per game while shooting 36.5 percent from downtown.
Green's game is being hindered by the same things that have held him back from being an elite player in seasons past, and he is not untouchable by any means. Green was someone that teams were calling about over the summer, and he likely still has solid value around the league.
The problem with Green is that it may take him another year or two to reach a level where the Mavs can play him high minutes, and he can consistently contribute. Dallas doesn't have time to wait for him to develop anymore. They need to go make win-now moves.
Green can still be a good contributor for this team, and his extension is at a good price, but the Mavs' window to win is small. He is also battling another elbow injury, and the Mavs could realize that they don't need him as badly as they may have thought over the next few weeks.
