I found it refreshing that they didn't do some kind of prime time let's get more ratings and dollars out of this.
They've had the show each week, so it's not like the Hoops tourney where you're seeing everything for the first time, or they can keep a camera on the team gathering for a bubble team. I'm guessing they wanted to give everyone involved (teams, fans) as much time as possible to plan.
Watching the show isn't important to me. Finding out the 4 teams as soon as possible is. Each of those fans going to games will know soon enough who the 4 teams are.
