I'm really surprised that Mandalay Bay is not doing anything to host this fight. It's probably the second "mecca" of boxing in Vegas, next to MGM. I believe MB's arena is a bit bigger than Garden Arena.
Yep. MGM Mirage bought out the Mandalay Group in 2004 I think. And the Mandalay arena seats less than the MGM's, so, they hold the bigger events at MGM.
MGM owns a good portion of The Strip. This is why there are multiple CCTV venues for PPV fights. & people thought a different city could compete with Vegas
