I couldn't have said it better. A lot of people look at the price game and say, there's one decision that cost them the game, and don't realize that
A. They may have also lost the game if they pulled Price after 7 or left Barnes in to face Cano.
B. What happened was a fluke, if you replayed that inning 100 times leaving Price in and 100 times taking him out, they would probably lose as many without Price as they did with him.
Take Abad over Barnes. Abad has given up 2 HR in 51 ABs vs lefties. Barnes has given up 4 in 69, but for arguments sake lets say he gives up 1 in 51 ABs. That means out of 50 times Abad would give up the HR once more than Barnes, so once in 50 bad decisions. If you factor in all of the other ways the runners could have scored it could easily be 1 loss out of 100-200.
That's simplifying the point as it's not about repeating the same decision, but the many different "bad" decisions a manager can make in a year. But the bottom line is these decisions are based on very small percentage differences.
