Hindsight is 20/20.
If Detroit converted and scored a TD... people will be saying that it was a great call.

Talking about calls... what about kicking a FG at the 3 yards line to end the 1st half vs going for a TD?
That to me set a tone for the Lions where it looked like they were passive in the 3rd quarter "protecting" a lead.

If you are going to be aggressive, then stay aggressive.
Not, let's switch to aggressive when the momentum is swinging to the Niners.

I bet internally, Dan Campbell regrets kicking that FG at the 3 yard line. Team responded in kind in the 3rd quarter.

To me, it's not about the 2nd half calls to go on fourth. I'm okay with that if he went for a TD on the 3 yard line in the 1st half.
