The Seattle Seahawks and Green Bay Packers will square off in the NFC Divisional Round on Sunday. These two teams have had some classic games in past postseasons and have a chance to create another this weekend. Seattle won a 17-9 battle in Philadelphia for the opportunity to travel to Lambeau Field.

The Packers are coming off their bye week that they earned for being the No. 2 seed in the NFC. They have the luxury of playing a home game with a trip to the NFC Championship Game on the line. This game will feature two of the league's best quarterbacks in Russell Wilson and Aaron Rodgers. There is no doubt that these two will show up on game day.

For Seattle, here are two other x-factors that they need to perform well in this game.

2. D.K. Metcalf

The Seahawks absolutely stole Metcalf late in the second round of the 2019 NFL Draft. The rookie wideout has improved every time he stepped on the field this season. Metcalf tore up the Eagles' secondary to the tune of seven catches for 160 yards and a touchdown. He made big play after big play in this game and that is what the Seahawks will need in Green Bay.

Seattle lost its top three running backs to season-ending injuries. This leaves them with Travis Homer and newly signed Marshawn Lynch in the backfield. They barely have a threat of any run game. This makes Metcalf's role even more enhanced.

He has been one of their top receivers all season long but has emerged as their No. 1 in recent weeks. Wilson needs his rookie to continue to perform well in this one.

1. Seahawks' Secondary

When playing against Rodgers, your secondary must always be on point. The Seahawks cannot allow Rodgers to get comfortable or else he will pick apart the defense. Seattle allowed 263.9 passing yards per game in the regular season. They must win the matchup this week.

Green Bay does not have a lot of talent at wide receiver. Outside of Davante Adams, Packers' wideouts have been mediocre. Rodgers likes to get the ball out quick. Green Bay throws a lot of passes into the flat and they feature slants and quick outs. Making Rodgers uncomfortable is also a job for the pass rush but he is good enough to step away and make a throw if there is an open receiver.

It is important that Seattle stays on the Packers' receivers all night long.
