Mason Plumlee got a 3/41 deal from the Nuggets. Right up there for the worst contract of the offseason. The only contract that I could say is definitively worse is Tim Hardaway.
I genuinely have no idea why they would do that. His qualifying offer was for less than $3.5 million. Ridiculous. He is lower on the center free agent list next year than Noel, Cousins, Embiid, Jordan (player option), Nurkic, Aldridge (player option), Favors, Monroe, Lopez, and right there with Dedmon (player option), Len, Kanter (player option that he'll likely take), and Koufos (player option). There has never been a worse time to be a center in the league and next offseason will possibly have the deepest center free agent class of the decade with very little money available for spending.
The more I think about it, I'm not sure that even Hardaway's contract is significantly worse because of the center market and where this is going to put the Nuggets against the luxury tax next offseason. They doubled down on the Nurkic trade by signing Plumlee to a terrible contract in hopes of saving face.
