Dumbest rule in football? I think it's Sudden Death (some interesting proposals circulating on this, guaranteeing each team a touch of the ball in OT). Coin flips shouldn't matter so much after a hard fought game. I personally love the college tie-breaker and fail to see why so many people are so against it. Seems the least "random" of the choices, but I've never played so take that with a grain of salt.

Oh, and while I'm at it, Touchbacks should be called Safetys and Safetys should be called Touchbacks.
