A wee bit confrontational, aren't we? One thing I'd like to make clear. I never said you can't be effective with little to no postseason experience. If that had been the case, I never would have nominated Buchholz to start Game 3.
I think that most baseball insiders would agree with me. When it comes to pitching, I'll take experience over exuberance most of the time. A veteran generally won't get too caught up in the moment and won't be overwhelmed on the big stage.
Here's a scenario. Two pitchers get hit hard to start a game. One is a rookie. The other is a veteran. Who is more likely to get rattled? Who is more likely to maintain his composure and gut it out?
That's probably not the tangible example you were looking for, but I don't really care.
