anticipating the call

[Nu1]

I recently read through a fairly intense thread on "Look at the feet" and the idea of passing on a violation that was apparently clearly seen. My thought on that was, if you see it, call it.

In like manner, I don't agree with calling something that didn't happen just because you anticipate that it might. Why not anticipate that the girl on the ground would roll around and commit a traveling violation and call that?

I admittedly have made an error or two by anticipating a play (like a foul) and calling it, only later to think, "I messed that one up." But I don't agree with knowingly calling something you didn't see.
