My brain says 'make the playoffs' but they way that last Sunday played out, it didn't hurt at all - unlike the previous playoff losses.
Thing is, we're not as upset about missing the playoffs because of the way the season unfolded. After Brady went on IR the expectations were quite low. The team improved and finished on a high note, so there was less of a sting.
Compare that to say, the Bucs, who went from 9-3 and 2nd seed in the NFC to losing the last four games, the last two at home, including a season ending loss to the Raiders. Making the playoffs or not would have meant a lot to their fans - as well as the HC and GM who lost their jobs over it. Conversely if they had started out 5-7 but won their last four games, their fans would have felt better about the team and Gruden and Allen might still have jobs.
