I didnt see the 2 pt conversion (I had dozed off), but that couldve changed the outcome too. The one Im talking about was a regular play. Mariota went back to pass and a KC player blitzed and hit him pretty hard, causing him to fumble. The Chiefs wouldve recovered it and maybe even returned it for a TD but the refs blew it dead and said the fumble didnt count because Mariota's forward progress had been stopped. It was one of the weirdest calls Ive ever seen.
