I am sure this topic or variations have been covered before, but searches on “baseball” and various forms of “LCS” didn’t show me a thread that seemed on this topic.
Clearly, the names “A.L.C.S.” and “N.L.C.S” for the American and National League Championship Series stink. No poetry. No immediate power in the name, as with “World Series” or “Super Bowl”.
If winning the league means you get the Pennant, shouldn’t they be called the Pennant Series? Any baseball fan would immediately get the importance of the name and how it means the league championship. It would have more history and meaning and would be a great lead-in to the World Series. “The Cubs have won the Pennant Series and are ready to take it to the Yankees in the World Series!”. You get the idea…
