Typically whenever a team acquires a big name, there is always a honeymoon phase until the team either has its first bad stretch since acquiring said big name of said big name's flaws start to show themselves. In the Utah Jazz's case, they are still very much in the honeymoon phase with Jaren Jackson Jr and will be for a while because they have yet to see what he will look like with the team fully healthy.
JJJ only played in three games with the Jazz, but it was clear how much he changed the team's landscape on his own.
