As far as the title goes, no they do not want Utah to win. If they had their way the championship would rotate among the big-market cities to garner the most revenue.
Take the last game. I'm just the final minute the refs missed, or chose not to make, 3 blatant calls including Rudy getting smacked in the head. Otherwise the game was reasonably officiated for the most part. But of course they had no reason to mess with the officiating until the last minute because the jazz more or less **** the bed in the 2nd half. They only needed to engage the refs to try to push the outcome in a different direction. So no matter what we will always have an uphill battle to get a ring. We'll always be playing 5 on 8. It's been that way since 98 and the last game where 3 blatant calls, combining for a 6-point swing, set up the final shot push-off which was also ignored.
So no, the league absolutely does not want the jazz to win a championship when powerhouse marketing teams are in the running.
