Attitude matters, the stats outside of baseball show that, no idea what they say inside baseball..... Talent matters a lot more in MLB than in attitude though. I also agree that it is generally a post hoc explanation, that really doesn't hold up to scrutiny well. When a team gets hot, and they say it is chemistry.....which came first, the more luck, or the new attitude? Attitude matters, 100% agree. How it is developed, how it contributes, lots of other questions.....we just don't have a firm understanding. And, picture and laughing while losing and all kinds of other stuff fans get worked up over, not a believer at all.
