WestMichBlue wroteSo - if we get a rundown between 1B and 2B the BU is going to cover that alone? I assume that I would have to come inside from the C position; do I find a fixed point to follow the action, or move with it?
Once the players decided to go for the runner going to 3B, should I have stayed on the backside (2B) of a potential rundown and expected PU to move to 3B end?

The initial action was a throw from home to 2nd, with both runners approaching. Seems to me your first priority on that is the lead runner and you can't come inside w/o getting in the way.
Then, if there is a rundown between 1st and 2nd, you can't loop around the outside of 2nd and still stay with the play, so inside it has to be, being sure to avoid the lead runner and any throw to 3rd.
All that is because the PU has to stay prepared for the lead runner at either 3rd or home, just like any normal 3rd or home coverage. Real nice if PU can keep lead runner covered and watch 1st end over the shoulder, but basically the BU is stuck with the whole 1st-2nd rundown. As said, the priorities of runners affect the coverage.
I would not recommend a fixed point, but you can't go end-to-end.
