Partly. If you decide there was no affect on the pass, then there's no need to wait to decide. If there was some affect, then it would be better to hold a second and see if the pass might be picked off.

I think it's the other way 'round -- if you see an effect, call the foul. If you don't see an effect, wait to see if you were right.
