I think with defense especially, you have your core principles. If you do those consistently, then it's easy to make, sort of, game-to-game adjustments. But, when you're not doing your core principles consistently, you end up just guessing a lot. To be honest with you, that's what bad teams do.
I always talk about shooting being broken down into three things. You have to have some semblance of good form. The second part is repetition: doing things over and over again until you really develop a skillset. And then the third part is confidence. But for me, you can't have confidence without having that second part.
You play 162 games so let's say 100 of them come down to the end where you see the game is out of reach one way or the other. I feel like the other 62 are close games so you're going to be into those at-bats. If you do that, that's 100 at-bats. That's almost a month worth of at-bats where you're not as focused as you might be in those 62.
