First one I have TD all the way. Receiver gets two feet down in the endzone while controlling the ball. And he's not going to the ground. So the play is over at that point, in my opinion.
If nothing else, it's a great teaching tool that the two covering officials should make some eye contact (and even quickly discuss, if necessary) before signaling two different things.
Second one could go either way. I said incomplete. But part of that is because of the "no cheap scores" philosophy.
Great clips.
