Completely disagree. Putting in an all or nothing guy who is very prone to the K with bases loaded, one out, for one AB in the 4th inning would have been a mistake. Who would you rather have later in the game, Branyan or MacGruder? Again, because it didn't work out, you consider it a mistake. If Branyan would have struck out, I am pretty sure you would have considered that move a mitake as well.
