When I asked about intent, I was wondering what the old commish had in mind when he made that rule. I agree that we should be able to change stadiums. Most leagues that allow it will allow you to draft a stadium at the end of the Free Agent draft every season.
A couple of the leagues i'm in have a "New stadium option once every three years" rule (Unless a new owner takes over, then they can take a new stadium, restarting their three year cycle)
That allows for change without costing an arm and a leg on one end, or allowing for constant change every season.
