McGee has been out since November, and there have been rumblings in Denver that his approach to rehab has been less than inspirational. McGee has faced questions regarding his maturity going back to hs time in Washington. In 2012, the Nuggets re-signed McGee to a four-year, $44 million deal.
The deal was done by then-GM Masai Ujiri in part to make sure that the Nuggets would still have his rights if he were to mature as expected. Many big men in the league don't reach their full potential defensively until they are 28. But McGee has never been consistent with his work habits or production.
The injury compounds with other injury woes for the reconstructing Nuggets, who lost Danilo Gallinari to a second surgery on his injured knee in January, and Nate Robinson who suffered an ACL tear as well. With the three players out, expect the Nuggets to apply for the injury exception with the leaue.
There's still a chance McGee could return this season, but for a team still trying to figure itself out under Brian Shaw and GM Tim Connelly, missing McGee could have lasting impacts.
