The "all penalties" idea is a longshot to pass, but I would be very surprised if they don't add reviews for something that is currently unreviewable. The NFL could allow challenges of helmet collisions because far too many of those are accidents caused by Newton's first law of motion, but still not make pass interference reviewable because it will always be a judgment call. Another proposal, letting coaches throw their red flags during the last two minutes and overtime, would not add too much time to the game because they still have only two challenges to use and may be out of timeouts that late in the half. Even that one is probably unlikely to pass. So many changes have been proposed most are unlikely to be voted on next week.
