Kobe Bryant is slated to make north of $30 million this season as the league’s highest paid player, a well-deserved honor for being in the final year of a max deal while playing in his 18th NBA season. But players are able to negotiate when those payments are made to a certain extent, and Bryant and the Lakers agreed to a scenario where he’ll receive a very large payment in a lump sum on November 1.
From Eric Pincus and Mike Bresnahan of the Los Angeles Times:
Negotiated as part of his contract, Bryant receives a balloon payment Nov. 1. On Friday, the All-Star guard will receive $24,363,044 from the Lakers.
Bryant’s salary for the entire season is $30,453,805 — the remaining $6.1 million will be paid out over the course of the season.
While there’s a limit to how much a player can receive in advance, Bryant is right at that 80% maximum.
