Team: Wizards
2016-17 stats: 31 G, 5.6 PPG, 4.8 RPG, 1.1 SPG
Salary: $16 million

Mahinmi had a lifetime average of 4.3 points per game in seven seasons leading up to 2015-16, and never averaged more than 18 minutes per game. Then, the departure of Roy Hibbert thrusted Mahinmi into the starting center position, in which he did a pretty solid job. Mahinmi started 71 games for the Pacers that year, averaging  9.3 points per game, 7.7 rebounds per game, and 1.1 blocks per game. And despite not having any real track record outside to back that up, the Wizards signed him to a four-year, $64 million contract last season.

This move had little impact on the Wizards this season. Mahinmi played in just 31 games this year thanks to lingering knee injuries, and his averages fell in every major category. Even if he plays like he did with the Pacers last season, you’re still paying $16 million a year to a backup center. This could also be a prohibitive contract if the team wants to add players to supplement John Wall and Bradley Beal.
