The main reason for the wrap-around coverage is because of the different time zones when they are at different cities in different time zones. I believe that Debbie Antonelli had stated it when she was pushing for a one site tournament where all 64 teams play. She stated that it would be easier to cover all the games without the wrap-around coverage which would be cheaper for the networks and more enticing for the fans. It would allow the fans to have a choice on which games they wanted to watch instead of the Networks dictating what they could watch. On the costs of having 16 sites with 4 teams at each site, then 16 teams at 4 sites, then the Final Four at another site. The Networks would save millions just having one city with like 4 to 8 arenas and play everything there, the costs of moving the crews would be a quarter of what it is now. Then she stated that the fans would be able to plan for the games knowing where their team is going to play because of everything being in the same city for three weeks. I believe she would be mostly correct because people could make reservation so far in advance that they would also be able to enjoy it more and have plans to where they could make it more of a vacation then just waiting until a week before the tournament and scrambling to get a hotel room, tickets, and plane reservations, so they could see their team.
The pandemic has been the impetus for lots of changes in our day-to-day lives. Like working from home. Ordering your groceries "on-line" and having them delivered to your door step. I remember her suggesting that concept a couple of years ago, but it never grew any legs............until now.
Depending on how it goes, having the tournament at one site may become the new normal for the NCAA tournaments. The participants will save money on travel costs. The networks will save money by not needing as many production crews.
The real winners in a scenario of this nature would be the fans. You travel to one city and stay in one hotel. You could buy one tournament pass, and see any/every game at any venue IN PERSON.
No doubt the coaches and athletic directors will have some input which may or may not carry any weight. I think the bottom line is the profit margin. I would welcome the opportunity to attend a tournament played at a single location AFTER this pandemic has been put to rest, and things return to normal, or as close to normal as we can get. If this thing goes over, and the reduced costs puts more $$$ in the coffers, it just might catch on. Remember the rule of thumb in big business: "It's ALWAYS about the money."
Enjoy the games.
