Are The Playoffs Different?

4th and 1 on the New Orleans four, and the Bears decide to go for it. Naturally, I approve. Neither of the announcers on TV agree with me. Interestingly, both announcers seemed to assert that the fact that this was an NFC Championship game increased the case for kicking the field goal rather than playing for the touchdown. But why would that be? I’m genuinely asking . . . thinking about it the relevant considerations in going for it seem to be simply the score, the time remaining, the yardage to the end zone, and the yardage needed for the first down. Are the playoffs different?
