Yesterday, I received messages from several long-term subscribers asking whether I had ever written about particular topics or pointing out an interesting event in football history. The messages point to two issues. One is that Substack has a search function, accessible via the magnifying glass icon in the top banner, to check on whether I’ve covered a topic in the past.

Click on the magnifying glass, enter a term, and you’ll see whether the term has appeared in the site’s 1,350+ posts. I’m happy...
