Three Seahawks rookies who could immediately impact the offense

Zabel was not only one of the top preseason rookies for the Seahawks, but throughout the league. In the first games played, Zabel was given an overall grade of 86.2 by PFF, with no pressures allowed. He was the third-highest graded rookie of all first-round rookies by PFF, only behind Indianapolis tight end Tyler Warren and New England offensive tackle Will Campbell.

Zabel will get his biggest test yet as a rookie in his first-ever start at the professional level. He will play against a 49ers defense that has a recent history of developing stout defensive linemen. How well Zabel can maintain his composure and toughness will determine how well the Seahawks offense plays.

Wide receiver Tory Horton

Among the Seattle rookies that made the most noise this preseason is the fifth-round draft pick from Colorado State. Horton looked athletic and nimble this preseason, much like he did before suffering a knee injury this past college football season.

His speed and separation skills have earned him the No. 3 wide receiver spot for the offense. With the 49ers’ secondary likely focusing on dynamic receivers like Jaxon Smith-Njigba and Cooper Kupp, it opens more opportunities for Horton. It wouldn’t be a surprise to see him make a big play in the return game first and then make several surprising catches afterwards.

Fullback  Robbie Ouzts

Fans of old-school football are going to love the Seahawks' new offense. The reintroduction of the fullback could easily be big for Seattle's rushing offense. Ouzts has already shown himself to be a tough, smart, and disciplined player against veterans during preseason games. 

Ouzts’ inclusion in the offense won’t be a surprise for the 49ers, who also utilize a traditional fullback scheme. Regardless, he is going to be that extra powerful blocker coming from the backfield to potentially help solidify the run game for either Kenneth Walker III or Zach Charbonnet.

Ouzts might also be a surprise pass-catcher for the Seahawks, much like he was for the Alabama Crimson Tide.
