Sean Marks' training camp extension deadline for Kyrie Irving, James Harden approaching fast with no deal finalized

NBA training camps open September 28 and Brooklyn Nets general manager Sean Marks put a self-imposed deadline for Kyrie Irving and James Harden extensions to be completed before training camp.

Kevin Durant already reached a four-year extension, but the second and third parts of the Nets' three-headed monster still need to have their futures secured. Of course, there is still time to lock up two of the franchise's cornerstone pieces long-term, but the longer things drag out and as the training camp deadline draws near, the more angst it will cause Nets fans, the more it will be a media storyline, and the more it will be a distraction for players. 

 It's far from panic time for Brooklyn, but the next 15-30 days will be critical in solidifying the team's off-season and ensuring top talent stays on the roster for the foreseeable future.
