Diaw's deal features $500k in annual performance bonuses in the form of a weight clause

Boris Diaw signed a four-year, $28 million contract with the Spurs this summer.

Per Yahoo Sports, Diaw is only guaranteed to make his full salary in the first two seasons of the contract; the third year carries just a $3 million partial guarantee, while the fourth year is entirely unguaranteed.

The most interestin portion of Diaw's contract, though, deals with those pesky pounds, as laid out by Amin Elhassan of ESPN Insider (subscription required):

Most importantly, Diaw's deal features $500,000 in annual performance bonuses in the form of a weight clause. Each season, he gets:

• $150,000 for weighing less than or equal to 254 pounds on Oct. 25

• $150,000 for weighing less than or equal to 254 pounds on the first Tuesday after the All-Star Game

• $200,000 for weighing less than or equal to 254 pounds on April 1

Basically, the Spurs have given Diaw a real incentive to make weight at three important junctures of the season: opening night, post-All-Star stretch and playoff push.

The structure of this contract gives the team some leverage to keep the player motivated while giving him an incentive to continue to perform at a high level.
