A Thing Maybe Worth Noting: Kenley Jansen’s Velocity
If I were to rank the months of the year in terms of difficulty of writing for FanGraphs, February would probably be #1; there’s just nothing going on in the second month of the year. The off-season is over, only the most meaningless parts of spring training are going on, teams aren’t aggressively signing long term contracts yet, and there’s just generally no real news on which to comment. February is the best month for me to take vacation, basically.
But behind February, April might be the second hardest month to write for FanGraphs, because while we have games to watch and data to look at, the overriding reminder of history that is drawing conclusions about anything this early in the season is probably foolish. Last April, Justin Upton was Babe Ruth. Last April, the Texas Rangers looked like the best team in baseball. April games matter in the standings and April performances do have some predictive value, but the samples are so small that we should rarely be willing to believe that a player has made a dramatic transformation from what they were before hand. Realistically, the conclusion of almost every data point we currently have is “That’s interesting; who knows what it actually means?”
But we still have to write about baseball in April, and we have to try and make it as interesting as we can. You don’t want to read five or six pieces a day that tell you to all the numbers right now are useless any more than we want to write them. But most of the numbers right now are useless, so we hunt for stories that are interesting and numbers that might be less useless than the rest. The overarching conclusion is still Beware Small Sample Size, but there are things that are least worth monitoring going forward. They might not continue, but if they do, it’s news. This is one of those things.
