Baseball, basketball, whateverball. One Sports Illustrated blogger loves the latest sports arena proposal right out of the gate:

While tourism is still the biggest driver in Vegas, those two million people need something to do during the hot summer, so why not a ballgame? The heat would require a dome, sure, but keeping it non-retractable would reduce cost, allow convention use, and let's be honest, Vegas knows how to handle construction. Gambling is baseball's third rail, but taking Vegas games off the books is a pretty easy solution given the low handle on baseball games. Probable? No, but it's possible. Just imagine the celebrities you'd see and the possibility of a Cirque du Soleil 7th Inning stretch. I'm a big fan of the idea, once Stu Sternberg or Lewis Wolff finally throw in the towel on their Sisyphean stadium quests. Now, what do we name them?
