As for the Jazz, they aren't really doing good and they are about to jeopardize their chance to be in the NBA playoffs this season. Imagine how they failed to maintain their spot for just a week, getting knockout from the playoff tree because of losing streaks.
You're right. The Jazz's performance has been really awful lately, considering they've only won 3 of their last 10 games. However, it's worth noting that the Jazz is still in 7th place in the Western Conference standings, and it means that if the Jazz's head coach finds a way to improve the performance of the players, the Jazz will still have a chance to reach the playoffs since the end of the regular season is still a long way off.
It was fools gold they were never destined to be a top team just had a hot start. They are stacking draft picks so I'm sure they like to see them end up in the lottery. This team going to the playoffs does nothing but ensure mediocrity. They gave up once they parted with gobert and spida.
