Running the ball there was the only smart option. Any intelligent coach would have called the same thing. The reason is simple.
The Cowboys were backed up against their own goal line. That means, any drop back would put not only the quarterback in the end zone but also the offensive line. Given how they struggled all day, you can bet every one of them would have been in or very close to the end zone while blocking.
If Romo gets sacked OR any of their offensive linemen get a penalty while in the end zone, it would be a safety. Taking a safety there would be worse than running and punting because at least with a punt, the other team would have to get a touchdown to beat you since a field goal would not help them. Taking a safety would have made it 17-15 and a field goal would have won it. That is not even considering the possibility of an interception or fumble by Romo that would have given the Browns an immediately touchdown and the lead.
The problem is that Moorman punted the ball low and directly down the middle. You could tell by his reaction that it was not what he meant to do. There are times to take chances, but that was not one of them. By running, they ran off clock time and forced the Browns to spend their timeouts. The defense failed to stop them after the punt return gave the Browns a short field. You have to have faith in your defense to stop the other team in a situation like that but with a short field, it made it harder.
Fortunately, there was enough time on the clock and the Cowboys had one timeout remaining so they were able to drive down the field can kick the game tying field goal to go to overtime. In hindsight, it is easy to say or ask why didn't they throw it, but at that moment, given the scenario, the right decision was made.
