Some coaches would play for OT but that’s true already.
Under this system, a team with 1st and 10 from the 50 with 7 seconds left could attempt a Hail Mary and the defense would try to get a pick instead of knocking it down. If it’s just an incompletion, then the team could just run a regular 2nd down play.
Can't edit, so just adding, I guess you are saying you take a risk for the win as opposed to playing for a safer chance at a lead in OT?
