"You must use a stadium from one of the franchises you have selected."
To me it doesn't matter. I selected one of the two from Yankee Stadium or Safeco.
I read the above to mean FULL franchises. BUT, I'd have no objections to anyone reading it as Musial6 did. If it happens, it happens, as long as someone doesn't pick outside of their franchises.
Thoughts? Absent Commissioner weigh in, are all three stadiums from your franchises ok with all?
