20 Most Immovable Contracts in the NBA

9. Bismack Biyombo

Bismack Biyombo has never averaged more than six points per game in any season of his career. But Biyombo did have a great postseason in a contract year and was rewarded with a four-year $70 million contract in 2016.

Now Biyombo is still owed $17 million this year and has another $17 million player option for next season. Biyombo has only played in 14 games this year and his trade value is limited to the fact that he will be playing on an expiring contract next year.
