Some brief observations:
The Mountain West tournament, taking place in Las Vegas, is using the same mountain-themed court as was used for last year's NCAA women's Final Four in Denver. (Thanks to Matt Rachmiel for giving me a heads-up a while back.)
The Atlantic 10 is playing at the new Barclays Center in Brooklyn. The whole midcourt area is saturated with advertisements.
I like the simplicity of the BOK Center court in Tulsa for the Conference USA tourney.
