On the Spector one, he actually did turn back to try to go for the ball. I would say that was probably the closest to PI, but we see stuff like that go all the time.
the first Elam one, both guys had hands on each other, when Elam let go, the receiver flopped. Again, to me that is not called.
on the second Elam one, if the receiver wants that call, he had to go back into the DB to generate the contact. Both Elam and the receiver were standing straight up with their arms up.
I think the only one I remember now that actually was legit was on on Cam early in the game near the end zone on that little slant route.
