The "Texas is more central" argument is idiotic, because the US is geographically big, to where most metro areas require a flight to other metro areas. It doesn't really matter if you're flying 1500 miles or 3000 miles -- it's still a flight.
If anything, Vegas is a better destination for people, because a lot of people travel there. There's not a lot to do in Texas as a tourist.
I think Chrissy bounced from Vegas because his lease was up, too many casinos had him banned, and he wanted to be close to Keithy.
