7 minutes is a lot of time, especially if you have all 3 TO's remaining. Some teams can put up 10 points easilly with that much time. There are too many variables to say it one approach is better than another. Has you defense been on the field all day? Are they tired? How likely is it they can force a 3 and out? If you think you can get two more possessions, at least if you are faced with a fourth and long within FG range, that's where you can take the 3 and play for another possession. If you don't have a good defense, and think you have no chance at two more possessions, you can go ahead and go for two, but if you don't convert, game over. Just like when a defender gets an INT and fails to go down with a lead... like the fumble Roddy White caused against SF, the defense should never extend the game. If an offense is behind, ALWAYS extend the game. Miss the 2 pt conversion, and the game is over. Take the PAT and the game is extended. Let's say the team that is down takes the PAT and then scores again. Are the odds better for the 2 pt conversion now? Is the defense on it's heels and more tired? In general, I say take the PAT and go for two on the next score. Momentum has swung big time, and the defense has to be more tired. I think the odds of success are greater after the second TD score to convert a 2 pt play.
