Its a legal minefield!!
Now lets say 2000 people are allowed back in.....you can reduce that to 1750 when you take off the vips and associated freebies! So how will it work? Season ticket holders may have to register their interest on a game by game basis, then that registration would close on a Wednesday (for a Saturday game), then there would be a ballot, and those successful would need to be allocated a seat somewhere and potentially have to print off their ticket at home.
If there were 4000 people allowed in, or in our case 3900 as that's 50% of capacity, you can take off the same 250 leaving 3650. More than enough for all s/t holders (2800 ish?) but then you'd still need to know who wanted their tickets to know how many left over tickets were available for purchase......and of course everyone would have to be seated safely in not necessarily their purchased seats!
Not going to be easy logistically is it?
