I think the single tourney location makes great sense. And I can only imagine the planning going into it. I just don't understand why, given this whole mess, the NCAA didn't initially push the damn thing back 3 (or more) weeks to build in room for makeup games, and time for some isolation and testing before it starts.
Seriously, is it all about "March Madness" branding? Were they actually worried about an empty period in schedules? You can always schedule more games, or spread scheduled games out if that unlikely scenario happened.
