The 6' limitation is a killer because it requires 3-4 empty seats between groups and, at best, using every 3rd or 4th row. Frankly, it doesn't make sense to me. I've thought (with no science behind this other than an understanding of geometry and air flow) that it should be less outside and more inside. For example, 4' outside and 8' inside seem intuitively to be roughly equivalent in terms of exposure to somehow else's respiratory output, particularly since it's believed you need to reach a certain viral load to come down with the illness so having it hang in a static indoor cloud seems much more dangerous.
This should be time consuming but relatively easy to implement for season ticket holders. It will involve moving people around so they might not get the same view they are used to, but it's easy to identify each account as a group of people coming together and putting a buffer around each one. It will be up to the account owner and ticket holders to determine if they want to risk exposure to others in their group (they may have to offer refunds to some that don't). But what do you do with students? There are no obvious groupings so how do you enforce social distancing? Furthermore, I assume the student section is GA (is it?) so even if groups are initially seated apart late arrivals, movers, etc. will quickly change that.
