Yes, they do. Players are paid by the NFL (not teams and not counted on the cap) throughout the post season on a per game basis with winners getting more than losers. It's not a lot comparatively speaking for the star players though even when they get to the Superbowl. And some players have clauses in their individual contracts that reward them based on playoff appearances. That was part of one of the incentives Seymour had in his rookie deal, and those incentives usually add up to a whole lot more because they either trigger base salary increases or roster bonuses.
