Here is my proposal:
-player family and friends
-staff family and friends
-recruits family and friends
-select number of fans may enter based on knowledge of Canes trivia. Do not allow the tailgating element (those who only attend games to party/tailgate and who couldn't name 5 players on the rooster. They only care about being seen on the jumbotrons flashing The U and dancing to reggaeton, mumble rap and house music).
I may be biased, but I think the "fans" category is going to start, end, and be defined by UM alum status and Hurricane Club contribution level.
Here are the real issues. Logistics and staffing.
For example, the NASCAR article quotes Daryl Wolfe, who is a friend of mine. I know how the NASCAR races are staffed, and there are different issues they will face at Homestead (near a major city) and Talladega (uh, NOT near a major city).
Racetracks and football stadiums do not have a large permanent labor pool. You are more likely to find regular employees at arenas that host multiple sports and concerts.
NASCAR hires a lot of temp employees (ticket takers and people who sell or vend beer/alcohol) and they use a lot of Boy Scout troops/cheerleading teams/local churches & charities to staff the food & soda sales stands.
So, yes, it may be easy to require masks or to restrict access to the infield, but it is going to be very difficult to get the personnel and equipment necessary to do screening/testing at the turnstiles. NASCAR races and football games usually hire off-duty cops from multiple surrounding jurisdictions (and rural locations have a tougher time), but it is going to be a very tall order to be able to get any sort of medical-trained staff such as nurses, EMTs, and/or doctors.
What this means for college football is very interesting, because the larger your (target) attendance numbers get, the more personnel you need to hire, both at the gate (testing) and inside the venue (food/beverage, ushers, ticket takers, etc.). If you are trying to hold a hundred D-1A football games (nearly all of which are played on Saturdays), then you have to try to get a massive number of off-duty nurses/EMTs/doctors to all of these stadiums (many of which are in rural areas with not nearly the same density of hospitals that you find in a city) in order to do the testing at the turnstiles.
So, yeah, I'd like to see capacity increased...but there are a lot of logistical and staffing hurdles besides just "stand 6 feet apart".
That's why I think the NASCAR "experiment" doesn't really prove anything. Putting 1,000 people in a 46,000 capacity facility, or 5,000 people in an 80,000 capacity frontstretch grandstand is not very much of a test of those logistics and staffing issues.
I hope it all works out, but I wouldn't expect this to be some indicator of how quickly football capacity returns to normal. If anything, it is probably an indication that capacity will remain low for the rest of 2020.
