I largely agree, but some of the in-game moves are important to both small picture and big picture. For example if you have a one-run lead in the 8th inning, do you use Kimbrel for 6 outs. It might greatly enhance your chances for that game. It might also make him unavailable for the next game at least. And if you do this too often you might burn him out early in the season. That's where the whole balancing act thing comes in IMO.
