Hypothetical: Does PI get called if KoolAid doesn't intercept the ball?

Not trying to go all out conspiracy, but from what I gather no flag was thrown until well after the interception and return. And there was comment about a block in the back. And I know often late flags are thrown for PI, generally after the WRs throw their arms up in disgust.

So, just asking, do you think the refs would have gathered themselves enough after quickly enough to make that call?

Let's not argue whether it was PI or not, just would they have called it a penalty if the play would have been over right away?
