Nice story. I'm glad you found OOTP again and that you're having this new found appreciation of fictional rosters. They're my favourite by far.
At first when you said Florence and was describing how the rosters changed daily I thought you may have been talking about this league in Italy I read about. "Frontier League" clued me in that it was probably American though and then I found out from googling that it's Florence, Kentucky, not Italy.
