I work with kids that are basically straight out of the age group from The Sandlot. Prime baseball age. In a state where you can play baseball year round. (Arizona) And I'll repeat what I've been saying here for a decade: MLB has a crisis on their hands. Kids don't care. More kids would know the Savannah Bananas logo than their local team. They'd likely be able to name more players on the Bananas than their local team.
Kids are not invested in MLB. There are some diehards, sure....but I think MLB's average fan (60, white, male) would be pretty shocked by how irrelevant baseball is for kids.
