This is a great run, I love that dodging tackles for 5 minutes works as a speedrunning strategy and as a playaround. It's possible to end input a bit sooner with a different ending strategy. Here's an example
that is 438 frames faster. I modified your input to kick a field goal with 50 seconds left, and then made a long kickoff that runs out the clock to 0. The longest kick return I was able to luck manipulate was 50 seconds of in-game time, but longer ones should be theoretically possible. It may be possible to end input by punting the ball with the score at 0-0, and manipulate the other team into catching it on the 1-yard line, fumbling backwards into their end zone, recovering the ball, and then getting tackled for a safety. This would be improbable to manipulate, but with the kicker at the right distance, it might be doable.
Happy Super Bowl Sunday.
