Because going for 2 has a success rate under 50%, while OT has a rate (pre-coin flip) of 50%. The only time you'd consider going for 2 would be on the second score, on the road, when you know you got very lucky to score the second TD (IE: They've dominated you, but you scored when the corner and safety tripped each other, or some other highly improbable and lucky scene).
IN other words, I find it very hard to believe that anyone would consider such a poll even remotely serious given the animosity in this poll, and the condescending, somewhat fececious attitude displayed by a few of the "kick it" proponents. When the 14 poll was posted, I took it to be a condescending joke. I did that because that math is relatively easy to see.
If I was incorrect, apologies.
My first impression at the idea was also that it had to be a joke, but upon reflection, I think it's clear that going for it is the smart play.Assume a 40% conversion percentage on 2pcs and a 95% conversion percentage on XPs (both assumptions are conservative). Also assume that you will score a second TD (because otherwise the entire discussion is irrelevant). Finally, assume that overtime is a 50/50 proposition. Here are all the possible outcomes:
1. Make the 2pc, kick the XP on the 2nd TD (38% probability)
2. Make the 2pc, miss the XP on the 2nd TD (2% probability)
3. Miss the 2pc, make the 2nd 2pc (24% probability)
4. Miss the 2pc, miss the 2nd 2pc (36% probability)
Scenario 1 results in victory (38%), scenario 4 results in defeat (36%), and scenarios 2 and 3 result in overtime (26%). Of those 26% of scenarios that result in overtime, 13% will result in a win and 13% will result in a loss. Overall, given our assumptions (that you score the second TD), going for 2 early gives you a 51% chance of winning and a 49% chance of losing.
Here are the outcomes if you kick the XP after the first TD:
1. Make the XP, make the 2nd XP (90.25% probability)
2. Make the XP, miss the second XP (4.75% probability)
3. Miss the first XP, make the 2pc on the 2nd TD (2% probability)
4. Miss the first XP, miss the 2pc on the 2nd TD (3% probability)
Scenarios 2 and 4 result in outright defeat (7.75%). Scenarios 1 and 3 result in overtime (92.25%). Of those 92.25% of scenarios that result in overtime, 46.125% will result in a win and 46.125% will result in a loss. Overall, given our assumptions (that you score the second TD), going for the XP early gives you a 46.125% chance of winning and a 53.875% chance of losing.
By those numbers, it's clear that the smart play is going for 2 after you score a TD when down by 14.
Now, you can get into the assumptions a bit and discuss the possibility of both teams getting extra possessions, but it's not nearly as cut-and-dried as you'd think, and the math isn't nearly as obvious as it first appears.
I'm not sure whether it'll affect your thinking, but what if I told you that the "go for 2" guys do understand that, but would go for 2 anyway?
Think of it this way. There are two possibilities: that you will make your two-point conversion (whenever you try it), or that you will miss it.
If you make your two-point conversion, it doesn't much matter what order you do your conversions in. Either way, if you score twice and prevent your opponent from scoring, you'll end regulation in a tie.
If you miss your two-point conversion, are you more screwed if you miss it with 7 minutes left, or are you more screwed if you miss it with 1 minute left? I would argue that if you miss your two-point conversion, you are more screwed the later it happens, because there will be less you can do to make up for it.
If you think your offensive play selection is limited after missing a two-point conversion with 7 minutes left, try missing your two-point conversion with 1 minute left. Your offensive play selection will be less than limited: it will be nil.
An excellent summation, but at this point it's like banging your head on a brick wall. That analysis has been posted, reposted, and repackaged several times now.If you make the 2pc, it does not matter whether you go for it early or late. If you miss the 2pc, it's better to miss it early than miss it late. Therefore, it's better to go for the 2pc early. The only potential flaw in the analysis is that it assumes that the 2pc and the ensuing TD are independent events- an assumption that the idea of "momentum" calls into question. Personally, though, I think the idea of momentum is pretty much just hogwash. I think basketball illustrates that concept far more clearly than football does, simply because there's a much higher volume of scores. Teams go on runs all the time and the announcers start talking about how they have "momentum", but the simple mathematical truth is that every single run is ended by a run from the other team, an outcome that suggests that the order of the scores is far more dependent on random chance than it is on any idea of momentum.
For those who'd go for two (which includes me), how many minutes would have to be left for you to change your mind? What if there were 13 minutes left, or 25, or 45?
As I said earlier in the thread, in my opinion, there are 3 criteria necessary for going for 2 to be a sound decision.
[*]I must be down by X scores
[*]I must be confident that each team will have X or fewer possessions remaining.
[*]I must need at least one 2pc at some point.
