I think the fake FG that became a punt shows all about the confidence Childress has in the D that Mike has created.
But if he was that gol 'darnit confident, don't you attempt the field goal & if you miss it, rely on that same defense to hold them aqgain?
That makes no sense to me.
They get the ball on the high probability miss and need two first downs to make it an almost for sure FG.
You put them deep in their own territory and they have to beat the D with a lot less liklihood of being successful.
Going for the 4th & 1 or a low probability field goal made no sense given the time left, D success, and time-outs left.
Put the ball into the teams strenght (D) not the weakness (O, long field goals).
