I dont see a problem with this at all. What ever you decide to call it these are still fans of yours that will come every game this season no matter how good or bad you play. I think the best way to describe one of those is a STH.
no it's not the best way to describe this number. season ticket holders buys 1 ticket for all season games at the start of the season. when i started this game it was confusing, why i do not get money at the start of the season from sth. in bb sth are more like a fan club.
