I've heard rumblings that a potential move to Las Vegas and selling the team has been a consideration for many years and that there's league influence from Silver and Co. to tap into the Vegas market.
Don't forget that the NBA is basically saying that legalized gambling is here and here to stay. The timing of this with that is a bit unnerving.
Jazz never drew well when they were in Las Vegas when they first moved to SLC. I would think the league would be upset about this. Utah is a shining example of small market success. I would be totally bumped if they left SLC and I no longer live in Utah.
