Players from the 2015 NBA Draft class are eligible for extensions this summer, including Minnesota Timberwolves big man Karl-Anthony Towns, New York Knicks big man Kristaps Porzingis, Boston Celtics point guard Terry Rozier, Brooklyn Nets point guard D'Angelo Russell, and big man Myles Turner of the Indiana Pacers, among many others.

With the beginning of the 2018-19 NBA season set to begin on Oct. 16, the deadline to get these deals done will be 6 p.m. ET on Oct. 15.

The Phoenix Suns have already taken care of their own extension-eligible youngster from the same draft class by signing scoring-machine Devin Booker to a massive five-year, $158 million deal earlier this summer to keep the former Kentucky Wildcats in their fold for the long haul. Booker is the only player so far to sign a rookie extension this summer.

Karl-Anthony Towns, meanwhile, could explore the market after next season, though, it has been reported that the Timberwolves are optimistic that the big man is going to sign an extension before his eligibility of doing so lapses.

Porzingis will be an interesting case because of his recovery from a torn ACL, as will Rozier given the Celtics' roster situation. The former Louisville Cardinals star can opt to ditch any extension offer that will come his way this summer for a chance to get a bigger deal in the summer of 2019, when teams have more money to spend and the salary cap is expected to rise to $108
