Since we have to play 2 games and (the 49ers game would be a certain home game for us) I'd have to say both.
Though I'd much rather we beat both as 2nd seeds (49ers 5h seed, Packers 6th seed, with the former beating the Bears at Soldier Field, the latter beating the Giants at the MetLife, then us beating the 49ers at home and the Packers beating the Falcons at the Georgia Dome. Then we face the Packers in a repeat and beat them down 42-0 to advance to the Superbowl and destroy the plucky NY Jets who - having replaced Sanchez with Tebow for the remainder of the season and won out, getting in on a wildcard berth - fail to score a point on our defense once again, forcing Rex Ryan to replace Tebow with Sanchez once again, and starting up the controversy all over again.
Ryan then trades Tebow and a (2014) first round pick to us for Flynn, Flynn bombs the season - he's even worse than Sanchez it turns out, and we become the first back-to-back superbowl champions to pick first overall, leading the NFL to change the rules so that teams from the North-West Pacific cannot pick first overall
