Advantage/disadvantage? Contact is contact, regardless of the impact on the affected player? If the evidence is that there was contact, even if you didn't see it, do you call it?

If you didn't see the contact, and it didn't affect the play, I wouldn't call it. Double that if you would have to pull the call from your partner's area. Some plays, we have to trust our partner had a better look.

Contact may be contact regardless of effect, but effect normally determines whether it's a foul. Look at the definition of incidental contact.
