Gobert is the most important player on this team (in a sense that he is the most difficult one to replace), especially defensively (there is no other player in the world that you could replace Gobert with and expect the same contribution on the defensive end) but also on the offensive end (Rudy sets great screens which is very important for a team that plays the way Jazz do, lot of passing, lot of movement without the ball). You can be without Mitchell or Conley and still play and compete at a high level, but if Gobert got injured, quality of the way this team plays would drop significantly. So yeah, Rudy Gobert, no question.
I also think Bogdanović doesnt get enough credit, he started out slow coming from that surgery, but last 6 or 7 games he has been really, really good. You cant ask more from Bogdanović than what he has given you for the past few weeks. Why is he never even in the conversation to be at the 3 point contest? This season he is at 42.1% and has shot over 40% for the past 3 seasons. Last season he was on 41.4 % on 7,3 attempts per game. These numbers are as elite as it gets, what does a guy need to do to even be mentioned, I mean, its ridiculous (didnt he make like 10 threes in 20 seconds or something couple of games ago, and yeah, this wasnt the first time)
