Denver's defensive rating is 16th for the season. Replacing Will Barton and Gary Harris with MPJ and Monte Morris is going to hurt their defense, especially on the perimeter and on the ball. The Jazz have had success against average and below-average defenses. They're going to get open shots in this series. They just need to settle in and make them.
Offensively, the Jazz are a much better 3pt shooting team than Denver. The Jazz generate more 3s and make more 3s than the Nuggets. Without Will Barton, the Nuggets lose one of their better volume shooters. They're replacing him with MPJ, who has been streaky. Jokic is shooting 31%, Murray is shooting 34%, and Torey Craig is shooting 32%. The Nuggets' best 3pt shooters are Jerami Grant and Paul Millsap, but they shoot low volume. Monte Morris can knock down open looks at 38%. PJ Dozier, who is their backup guard, is a non-shooter who makes around 28% of his 3s.
The Nuggets' game plan is pretty obvious. They're going to try to pound the ball in the paint, draw fouls, generate offensive rebounds and wear the Jazz down. Nuggets like to use their bigs to handle the ball and back down--not just Jokic, but Millsap and Grant as well. The Jazz need to put enough size on the floor to offer resistance. This is where guys like Brantley and Morgan can play a role, just by staying between Denver's bigs and the basket and using their size.
