This. Kapler appears to still approach the game with the mindset of a player. Win now. Tonight. This inning. This AB.
Players (except to some extent catchers and pitchers) need this mindset. Focus on the current situation. Don't worry about later.
The manager needs to be balancing the immediate need - what's best in the moment - against the club's needs later in the game, and in the next couple of games. Moreover, as any manager in any business, he's responsible for "employee development" - putting his charges in positions where they can excel, protecting them from situations where they're likely to fail, paying attention to their workloads. This is no different than a manager in an office, with a dozen subordinates. It isn't just about getting to 5 pm today; it's about maximizing the unit's productivity on an ongoing basis.
And the GM? He has to balance the current staffing - do we have the people to achieve our goals in place now? - with longer-term concerns and needs.
This is pretty basic management... and as of now, Kapler, IMHO, still focuses too much on right now.
He was right in the post-game. It was a crap situation. But he helped get them into that situation.
