Here you go. This was the post I made to the guy who posted about stats when a team is down by 9 points:
Here's the thing. There's no tactical adjustment to make if you miss the 2-point conversion that late in the game (Iowa only had 2 TOs). Game's over no matter what if you miss because there was less than a minute left. Team just has to kneel on the ball to run out the clock. Of course the stats are low because most teams never recover the onside kick or they fail to score a TD, not because they get an onside kick then score a TD and THEN miss a 2-pt conversion. Just sayin'.
- When down 9 points late-ish, there’s a case that you should go for 2, because being down 8, you would have to go for 2 to draw even eventually anyway, and it’s better to know whether you converted your attempt earlier so you can make tactical adjustments. Although this logic seems sound, the data doesn’t suggest the effect is very significant (if it exists at all).
That article said that there was a 2.9 percent chance to win if you go for 2 and a 3.4 percent chance if you kick the XP. But that only applies if there is enough time and enough timeouts to get the ball back if you miss the onside kick. If it is a situation in which it is absolutely essential that the team gets the onside kick then you go for the XP first.
I apologize I didn't read your later posts, but there was still technically enough time to get a quick fg and another onside. Although extremely unlikely.
