Snap goes over holder's head, holder fumbles the snap, holder leaves laces pointing towards kicker, kicker mishits(whiffs) ball, kick is blocked and returned for two, etc, etcStill much more risk running said play: snap goes over QB's head, QB fumbles snap, QB wiffs on the play, QB is stuffed, QB throws pick and they take it the other way for 2, etc., etc.For a long time now I've thought you could set up for a play, have the QB call for motion, and then decide whether to kick or run the play based on the QB's read. If the D didn't react to the motion correctly, and you ended up with a mismatch, he would run the play. Otherwise, the QB would take the delay penalty, and you'd just kick a 7 yard extra point. If I was coaching I'd seriously consider doing this every time. I mean, how often would you miss a 7 yard extra point? Even if you only ran the play (instead of taking a delay) 20% of the time, it seems like it'd be worth it.
Just playing devil's advocate but if you are looking at everything that can go wrong no offense would throw a pass either.
