So, the Panthers O-line didn't show up to play at all!
Also, who else knew that the head referee of that game has always produced a win for the Broncos (6-0 when he refs, including SB50)? And it showed; that Fumble recovered for a touchdown shouldn't ever have happened. Panthers should have had a first down at about their own 40, but the catch was ruled incomplete. After replay and review, the announcers said it should be a catch, and still the refs said it was "inconclusive". It didn't cause the loss, but it sure helped and was a large momentum swing early in the game.
I maintain that someone was not doing their job right, and it wasn't Cam or the Panthers D.
