I am assuming he would have nailed the FG and it still makes little sense to me to kick it.
You are hoping for OT if he makes the kick, with an outlier chance you can win the game in regulation by getting the ball back with a 3 and out. You are essentially hoping for a likely < 50% at a win. You're putting everything on the defense, which has not played well, whether you make or miss the kick, too.
Why are we paying this guy $220 million if we don't trust him to convert 4th and 2 against the Cardinals?
The touchdown putting them up 4 was a HUGE advantage. Forcing AZ to have to go the length of the field. The only mistake I thought of watching it was that they scored too fast.
