Vegas once had the greatest professional sports team..The Computer..they could throw the bomb, run it up, hit the middle, score big when the buzzer sounded, & run the reverse like nobody ever has or ever will...just kidding.
I, one day see LV with possibly an NBA team, especially if UNLV Hoops continues to falter(as college ball doesn't appeal to all, even when it's a winner), and due to the NBA being a bit less rigid than MLB or the NFL in puritanical forms, also due to the raised attendance & population/demographic demands of the NFL & MLB in needing bigger markets.
With Az D-backs and LAD within proximity, you can bet that MLB, with an office that has had it's fill with gambling related matters, will not come calling.
With the NFL need to get a new stadium for Super Bowls back into the warm weather of the nation's #2 market, it's assured that LA will be the NFL's next expansion city..even if LA fans will show up late and leave early to catch the finish of Rams and Raiders games on the dish.
LV would show up 70K strong for an NFL team, yet the NFL would keep a team like the Cards in a town like Phoenix, just because it's a fast-rising #4 market in the US(regardless if they like football or not), and play the gambling card as an alibi..what a shame.
Even if LV didn't support teams the way a city of 1 million should, the sheer volume of tourism alone would guarantee that any venture by major pro sports would thrive.
Then again the leagues don't want a home team to have fans erupt in jubilation as the home team scores a "hail mary" to backdoor the number as the clock expires on a tv loss, nor have NFL Films show the massive garbage of torn and tossed Sportbook tickets flying, as the backbreaker bomb versus LV puts the game on ice.
