Kawhi Leonard is holding firm on his desire for a maximum contract, and extension talks with the San Antonio Spurs have failed to gather traction despite a looming Friday deadline, according to sources.

No progress has been made despite discussions for weeks.

Multiple league executives believe he'll command a max offer sheet on the market next summer.

Leonard has missed the preseason with an eye infection and is unlikely to be in the lineup on Tuesday for the Spurs opening night game against Dallas.
