Seriously, that could be pretty cool. Vegas has several facilities where they could do a thing like the Olympics where games are played in a smaller area. Some would be for the premier events (the incredible Raiders stadium) as well as the Golden Knights, UNLV and MGM sports venues.
The challenge is...well, I have it from a good source that the NBA will NEVER have their all-star game there again. Way too much damage control had to be expended.
And has everyone seen the new sphere? What a venue!
