Walker Kessler has been a great story for the Utah Jazz, all things considered. His rise into becoming one of the NBA's best two-way centers, even if he's not a scorer per se, makes him a building him block for their future. Making it even better is that by pairing him with Jaren Jackson Jr., the Jazz finally gave Kessler the defensive partner-in-crime he's been desperate for all these years.
The Jazz's defense has consistently been among the NBA's worst. One may get the wrong idea that such a problem proves Kessler's not as good a defender as some would think, but really, the issue is that Utah's defense has been that putrid despite his effort, as he is just one man after all.
