Not many managers bat catchers leadoff. They are slow, they don't play everyday, they get beat up as it is, those are some of the reasons it's not realistic. In Hanigan's case, he may find less playing time in the near future. I happen to find the concept interesting, but it doesn't bring me to revolt against Dusty at all. Hanigan is performing effectively as the 8th hitter that helps turn the lineup over, etc.
