I mean, that single decision is as bad as any decision we have seen.
You can't lose that game and never pitch him.
How much did it effect the team, players and organization? Who knows but when you do that and you lose your chance to win it all, a chance that may never happen again, you tend to get pissed and understandably so.
I don't think any of us have any idea how much impact it truly had.
I think it was a real bad screw up, with a doubt, but I think it has little to do with a players mindset when they are on the field. This team was turning south even during that play off year. I honestly feel like it is something players, will talk about years from now, but I don't think it has a great effect on the following years team.
The team had no speed, defense was ignored. The bull pen, like all bull pens that was the strength, became less effective, and the rotation, especially the last 2 years was terrible with no back up depth. The line up became more one dimensional each year.
