The Key to the touchdown touchback is simple. If you watch the earlier kickoff after the Bills score the same player rightfully downs the ball in the endzone. He doesn't toss the ball to the ref, he looks up field realizes bringing it out is not a good idea and takes a knee. HE KNEW THE RULE. By tossing it towards the ref he had a brain fart but that should not have causes the Bills points. It was the players mistake and it cost the Bills.
