The 2017-18 NBA season continues to fluctuate for the Denver Nuggets. Aside from falling in and out of the win column over the past several games, the performance of big man Nikola Jokic has been inconsistent as well.

Jokic recently got called out by teammate and veteran forward Richard Jefferson for not being the Nuggets' best player night-in and night-out. Jefferson followed up his criticisms by saying he is unsure whether or not “The Joker” could become a vocal leader, according to Harrison Wind of BSNDenver:

“No, he’s not a vocal guy. That’s not his personality. I don’t know if it ever will be. But Tim Duncan wasn’t very vocal. You can lead by example and I think that’s the type of player he is.”

Although Jefferson's remarks may seem a bit harsh, there is plenty of truth to what he is saying. Jokic recently had a monster game versus the Memphis Grizzlies, where he went 11-of-17 for 28 points, 13 rebounds, and eight assists. However, he followed up his stellar performance by registering just seven points and six rebounds in Denver's blowout loss to the Utah Jazz on Tuesday night.

There was speculation that “The Joker” would take on a larger role with the absence of veteran forward Paul Millsap. If he is going to do so, he may want to learn to channel his inner Tim Duncan.
