A steal for a penny

There has been an increase in coverage and analysis of pro football in the 1920's. However, I've been disappointed with the lack of semi-pro, company, and town team football coverage in the same era. It's primarily collegiate to the early formation of pro football after WW1 that is written about. I understand the Packers were/are a town team, but thinking much smaller scale. Or, perhaps I am not reading or looking for the right books.
