Player A: 0/4, hit 4 110mph rockets right to the RF
Player B: 0/4, 4 strikeouts, walked up to the plate holding his bat upside down for the 4th AB
What player do you feel better about coming out of the game? This is really simplifying the argument by exaggerating an example but the results were the same despite one player playing really well and the other one sucking.
Now make the example less extreme, add a few more pieces of data and stretch it out over a much larger sample and you have Ian Happ. Will he suck all year? He might! But it’s much more likely he will start getting better results doing the exact same things he is doing now. (Also as others have pointed out Happ really isn’t “sucking”)
But what if the results never get better? Then he may be an outlier and over a large sample it becomes clearly that for whatever reason this person always underperforms his expected numbers. Or overperform if we are talking about someone like Kyle Hendricks in his prime. Analytics always suggested he should be much worse and he wasn’t. Ian Happ has played enough baseball to know he’s not one of these outliers.
Ive had these results vs analytics arguments several times and I find it hard to change the mind of the type of person who insists results are all that matter. That’s fine, I’m pretty sure you know what these numbers mean, you just don’t care enough to change your opinion. Just know that like others have said every other team is making decisions based on this type of analysis.
