Down by 2 touchdowns, go for 2 theory.

[valenzuela]

So lets suppose team X is down by 14 againt team Y, there is Z( i dunno the value of Z but i do know z is a positive value) time left. Team X should go for 2, here is why.
If team X scores another TD they will regret going for one on the long run
If team X scores two td here are the outcomes:
If team X goes for one one the first TD they will lose 1,594% of the time.( trust me, do the math by urself)And they will force OT on the other games.
If team X goes for two they will lose 36% of the time, they will win however 39,6% of the time.
So why dont teams go for 2 when theyre down by 8 late on the game??
Here is the val theory( who was stolen from somebody else i dont remember)
