As for the play in question I did think it was a catch. So?
7 point swing.
Get a grip!
7 point swing? Really? Even if the Panthers get the call, the exact same thing happens on the next play for all you know. All kinds of questionable calls and non-calls happen in every game. The Broncos manhandled Cam last time they played, they did it again this time and they would do it again tomorrow. END of story.
