Nikola Jokic -- an All-Rookie First Team honoree last year -- had a rocky start to his sophomore campaign in 2016-17.
The Denver Nuggets and their head coach, Mike Malone, experimented with a twin-tower frontcourt to start the season, with 6'10" natural center Jokic playing power forward next to 7'0" Jusuf Nurkic at center. That pairing lasted a grand total of eight games and 103 minutes played, in which they posted a horrible -15.4 net rating together.
The two bigs have not played a single second together since the experiment was abandoned after a November 10th loss to the Golden State Warriors, and it's starting to look like it will be a timeshare between the two at center in every sense of the word going forward.
