OK but the point is they would have to drive further if you go and don't get it. A FG won't beat you only a TD. They only had to go 70 yards instead of say 96 if we go and don't get it.
I just got my power back so I haven't had time to look but I think the expected win % or whatever it's called is about 25% higher if we go for it than if we kick the FG. A friend of mine is a Vikings fan, she watched the first half got home, saw the score and then watched the 2nd half and first thing she messaged me was why the hell did you kick the FG that was not very good math.
Even if we throw the ball on 4th down and it's incomplete, we still use a few seconds and they get the ball at the 4, not the 30
