Not so long ago, the Celtics had five centres; Perkins, Shaquille O'Neal, Jermaine O'Neal, Rasheed Wallace and Semih Erden. They had more centres than they had roster spots for them, and had done it this way on purpose. But Rasheed followed through on his retirement plans, Shaq has struggled to stay healthy, and Jermaine lost that same struggle four years ago. Not even Erden exists any more; like Daniels, he and the Skillz Train were pawned off to the Cavaliers in exchange for a second round draft pick, simultaneously opening roster spots and saving money. Without him on the bench, the Celtics become even shallower. The team that has to go through Dwight Howard now has to do so while relying on Nenad Krstic and Big Baby at centre.
There follows a list of all current NBA contracts that feature trade kickers, in contracts valid as of the time of writing, along with the value of them. Note that trade kickers have no expiry date other than the expiration of the contract itself, and that having a percentage listed means that's the percentage of their remaining salary that they will additionally get with the bonus.
Note: Non-US teams that the player
has played for are, unless stated otherwise, from the top division in
that nation. If a league or division name is expressly stated, it's not
the top division. The only exceptions to this are the rare occasions where
no one league is said to be above the other, such as with the JBL/BJ League
split in Japan.
