I used EV (expected value) from the "poker slang". But anything else goes that describe rewards/risks.
Again: A 0-14 score is the same "worth" as a 25-27. It changes nothing. It´s still a loss in a very short 16-game season where every W counts tremendously much.
Coaches who trust their players, who may fail in this or that 4th down, certainly get the rewards later if not instantly. Even defense players welcome 4th down tries. They feel "pumped" up given the task to defend a short(er) field when their offense didn´t convert. It´s all up in the interviews they gave now and then. I trust talented players more than fat coaches whose only concern is their personal gain/face saving. The thinking goes (as Easterbrook once described): If the players lose a close game the blame can be shifted to them (or the refs, luck, weather, whatever). But if risky 4th down conversations fail, normally the HC gets the blame... Cowards!
There is no law in football that says you can only try to convert 4th-and-1s...
As Alpe most recently and countless serious studies showed: Going for it, up to 4th-and-10+, gives you higher rewards than kicking/punting. Now I don´t ask coaches to go for it every time (especially not if you are in a comfortable lead in the 2nd half), but kicking 4 straight FGs going up against the heavily favoured Patriots won´t save your day. Norv tried that trick once in the playoffs. Ryans blunders come close to that recreancy for the "enemy". People who act like this are normally yes-men to them ranking above, and little dictators to those below them. I only feel disgust for such people. Fat Ryan made his way up to the my personal $hit-list right up to the class of a$$holes like Horner and Norv...
