So we'll be doubly screwed if the Brewers don't seize homefield advantage now because adjustments aren't being made home/road. The Brewers aren't competing in the playoffs next season or last. They're competing in the playoffs this season. And this season he's struggling on the road, while that's occurring to Marcum at home. You don't think they are aware of that which in turn effects their performance until there's a game or two which turns things around for him in that department. Athletes in sports (especially in baseball which requires preciseness of movement) are streaky overall and situationally and they'll acknowledge it comes down to confidence. You'd refer to that as "anecdotal evidence", a buzz-phrase to deligitimize the information, but you could also classify it qualitative research. And while quantitative research is more reliable on average because it's not as prone to bias (although it is from the interpreter), qualitative research has the potential to be more valid because more variables can be accounted for. For example, you're using standard deviation to pawn off extreme ups and downs as luck because they more or less average themselves out over extended periods of time. However, what is to say there aren't causes to the ups and downs though, especially when numerous ballplayers themselves would tell you that is the case. The events aren't anomalies if they are extreme and frequent. Rather, the opposite is the case. They are tendencies. Greinke and Marcum have established a tendency in the present which requires being adjusted to if possible. And the Brewers established this year that they can't win on the road. It was a tendency! ...until they started doing great on the road and that tendency disappeared. The problem is that people in general have a poor feeling for when luck is no longer the most likely explanation for some statistical anomaly (me included). 162 games seems like an eternity! If a tendency can keep up for that long, it FEELS like it has to be real. But when you actually start running the numbers, you will often find that statistical noise is still likely the largest contributor (although no one will ever know for sure). It's that damned buzz word, "regression to the mean". You are suggesting that there might be a skill-based cause for Greike's extreme home/road split this year and you may be correct. Who knows? But you are absolutely incorrect in suggesting that their is evidence that it is an "established tendency". Perhaps Grienke has a larger than average expected home/road split but the statistical evidence for it is weak. And you speak or quantitative evidence but provide none. You didn't even provide anecdotal evidence. All I see is your 100% unsubstantiated opinion (sprinkled in with a condemnation of quantitative research). If you have some actual evidence (other than the split itself of course), please share it.
