It’s common for fans to lament their club’s lack of catching depth. When looking up and down a lineup, trying to find the best areas for improvement, the backstop’s batting line is likely to stand out. I’d argue that this is often misguided— how many offensive threats are there at the position leaguewide at any given time? Not many— but it is definitely important for teams to maintain a steady supply of catchers who are capable with the mitt if nothing else.
