This is a football one that I listen to quite regularly. It's hosted football ambassador and collector Bob Swick. I'm not sure if he is a member, but I know his cohost is on here (Joe S. "Publius").
It is quite enjoyable if someone is interested in starting a baseball one in the same style. I was fortunate to be a guest to talk about my Army football collection.
