Was Mike Smith's decision to punt the right one?

Here's why it was a bad call: http://www.advancednflstats.com/2010/12/should-falcons-have-punted.html

The thought process leading to the decision, not the outcome, determines whether or not it was a good or poor decision. In this case, it was a poor decision. Heck, they beat us in the first game primarily because they went for it and converted on 4th downs.

Granted, I'm happy that Smith chose poorly, but still...
