A previous topic reminded me of the aborted PI replay rule that spawned after the Rams-Saints NFC Championship from a few years ago. What a terrible idea, and at least the refs blew it off by overturning something like 3% of all PI replay challenges. Other dumb ideas:
*Rotating home-field advantage for postseason through mid-70s
*Rozelle Rule/"Free Agency" - you can sign free agents, but Pete Rozelle will decide the 'compensation', but only after you sign your free agent, making everyone involved upset.
*Goal posts placed on the goal line - perhaps the dumbest idea in history.
*Bonus draft pick in 1950's - why?
