Percy Harvin vs. Packers Secondary
The Seahawks will finally have the opportunity to reveal the full capabilities of one of the league's most explosive weapons in the form of Percy Harvin. Harvin missed just about all of the 2013 season before breaking free for a kickoff return in the Super Bowl.
The Packers' secondary allowed 247.3 yards per game through the air last year. Green Bay used their first-round selection on safety Ha Ha Clinton-Dix to help shore up the secondary, but that's hardly a guarantee of improvement in Week 1.
Expect Russell Wilson to find Harvin often to keep drives alive and to create big plays.
Seattle Front Seven vs. Eddie Lacy
The Legion of Boom appeared to be in midseason form throughout the preseason, after finishing the previous season as the best pass defense in the league. While it's safe to still expect some solid ball movement from Aaron Rodgers and his receivers, running back Eddie Lacy could easily become Green Bay's relied-upon form of offense.
Red Bryant was cut loose from the Seahawks roster, despite being a vocal leader, team captain and a mainstay of the defensive line's run-stopping force. The Seahawks replaced him by bringing in Kevin Williams, but the results may vary.
With Seattle run defense being a little softer than the pass defense, the Packers should test the Seahawks' new defensive line often.
Seahawks X-Factor of the Week
One of the key additions the Packers made over the offseason was adding Julius Peppers to the defense and shifting him from an end to a rush linebacker in their 3-4 defense. The addition puts a quality pass-rushing threat on the opposite side of longtime Packer Clay Matthews, meaning he cannot be double-teamed as readily as in previous years.
The Seahawks' offensive line has looked solid for most of the preseason, but with teams now scheming and blitzing, the proof will be in the pudding. While Russell Wilson has looked like a quarterback ready to take another step in his development, he'll have an awfully hard go of things if he's under duress throughout the game.
Rookie right tackle Justin Britt has been especially susceptible to being beaten in pass protection, and Seattle will need to give him help from a tight end or someone in the backfield to keep Wilson upright.
