I think they tried to take the team to the next level, and they made what seemed to almost everyone like good moves. There's a reason the fans and media had the Jazz listed as title contenders before the season.
What's wrong? It's hard to predict chemistry issues and Quin Snyder is a mediocre coach. The primary reason the Jazz have been a 50 instead of 35-40 win ball club the last few years has been the defensive presence of Rudy Gobert and a good mixture of personalities.
We still have Gobert of course, but the chemistry issues and poor coaching are destroying us.
