I agree.
I think Dez was by definition PI'd with on the last play.
The defender wasn't looking at the ball and while the shove looked slight, he did have his arm extended. That's a point of emphasis on PI calls and we didn't get it.
On the other hand, they call a PI on Claiborne who is looking at the ball. He kinda gave him an arm bar, but he wasn't grabbing the receiver, he didn't interfere with the WR's progress, he didn't push the receiver and you could probably call that incidental contact from hand fighting since both were looking at the ball.
There was another pass play, I can't remember to who, but the TB corner had both arms extended and was grabbing the Cowboys WR before 5 yards (legal), but then continued to do it for another 5-8 yards (illegal). And there was no call.
