It isn't that crazy.
Giving the Seahawks a short field makes sense. The Hawks don't score TDs in the first half and are one of the worst first half scoring teams since their game against the Rams. You can give them the ball in the Red zone and it still likely will only be a FG. We have a terrible TD to FG %.
Worst case you give up a FG. Most likely the Seahawks give you the ball back with a punt. And going for it on 4th down gives you a better shot at the TDs you want. In our Last game against the Rams, the Rams scored 2 Tds on separate drives by going for it on 4th down.
Edit:
That was a beautiful TD. The numbers say they cannot run the ball or score TDs. But man, I hope the Hawks prove the #s wrong. Maybe we can break the trend.
