You play the game based on what you have witnessed all day.
In this case, the Dallas defense was shutting the New England offense down.
I don't care if you have the Pro Bowl team out there, when the defense is getting the job done and the offense isn't you go with what brought you that far.
Killing the clock and relying on one more stop was the right call. Now, I don't care for the formations they used because they were pretty much big flashing billboards that Dallas was going to run.
With a weak OL, you cannot allow the defense to stack the box. The OL was having trouble blocking 3 and 4 guys but we ask them and a couple of TEs to block 7-8?
Running was the correct call. Telling the Patriots you were going to run was not.
