Well, I think it probably is more complicated than that. I'm certainly no expert, but off the top of my head, there are several factors that must be considered: how often the arena is used; whether the arena is surrounded by large parking facilities (thereby cutting it off from the surrounding community), whether the sports team gets a percentage of revenue from business within a certain proximity, the accompanying infrastructure serving the area and nearby areas, etc.
Yes. There are stadia with no parking. Light rail connection to a parking area is possible. There a lot of variables.
