I've never seen a botched snap in a kneel-down situation in 35 years of watching football, at any level.
The closest was that infamous Giants-Eagles game in the late 70s when Herman Edwards returned a fumble for the winning TD when the Giants foolishly tried running a play instead of kneeling down.
So I don't know if a botched snap in a kneel down has ever happened in the history of football. If it hasn't, why should it be in Madden?
