The rules do call for a forfeit under such circumstances, and I say give it to them. 1-0, Yanks.
Hell, give it to them 22-0; they need a little something-something to make things kosher again.
When you lose by 3 touchdowns and a 2-point conversion the week before, you win anyway you can - even if your opponent is 20+ games behind you and just went through a major hurricane.
