I would agree in college that most teams would know in advance who starts game 1. as it is usually the ace, who you can being back later in game #2 if the #2 gets into trouble and the game is close. I can see no decision being made if the staff is weak , not consistant and you need to see them warm up to get an idea of who looks better. or if you have a book on the area umpires and do not know who is going to be behind the plate, certain umpires have a wider strike zone then others, to pitch someone who lives on the outside corner and can not get a call is not a smart coaching decision
