"Not necessarily true. I can move and turn my head at the same time"

As we all know that is an awkward running position and why should you have to when the base umpire has all of this in front of him?




"The BU isn't going to realize s/he needs to cover 3B until the runner has two steps in that direction and will never outrun the player."

Most of the time the runner isnt going to make a move to third until s/he slides or slows up coming into second, giving the BU even more of a jump ahad. Any experienced umpire is going to realize s/he is possibly going to need to cover third as soon as the ball gets passed the catcher. Anticipation is part of umpiring and so is hustling. Using these two tools , you wont be as far behind the runner as you think when you set up for your call

And since none of this is covered in the book it is, in fact, opinion. Pregame it and do whats best for you when the situation arises
