Kind of a new analytics thing, but the math actually says it's the right thing to do, when down 14. You have a little less than 50% chance of getting a 2 point conversion (probably not exact math but I think that's what I read when researching this), so if you get the two point conversion, then you'll be down 6 and only need an XP to win if you score again. If you don't get it the first time, you have to go for 2 a second time to force OT. I'm not sure if I totally agree with it yet but it's definitely becoming a new thing. It's happened a few times in college football the past month
There's some good stuff to back you up and go in a little more detail here.
