This is where I'm with you. A players results is a factor of many events above and beyond inherent general skill. In this case maybe Getz can see the pitchers release point better or something like that. If he can then it makes sense to bat him higher. How is it radically different from left-right splits. That's an accepted difference.
I've seen the impact a good manager can have on a game. Gibbons never had that. People are now jumping on him because of a few games with confusing moves. That to me was the tip of the iceberg.
There was once a joke about this. The purpose was to clap and high 5, but truly torelay the call from the 3b coach and provide argument if safe at first while timing the pitcher. It's the least important coach.
