Saw this interesting article on fourth down decisions on SBnation. Don't remember seeing it in the past couple days and no hits on a quick board search.
Makes sense that the decison is different in college than the NFL. Also interesting, though unsurprising, that the calculus changes if you have a kicker with a big leg (WILD THING!). It would be interesting to run the math on how this changes depending on other offensive S&P+ metrics; e.g. I would expect a team with good offensive efficiency would be better served by going for it on fourth down than an inefficient one.
