While so much attention has been given to the Seattle Seahawks’ 2019 draft class, it is the smaller, but very effective class of 2018 that could make or break the Seahawks season in 2019.

Coach Pete Carroll has long preached his belief that players take the “second-year leap,” which is a big jump forward in production from their rookie year to their second season.

Seattle is returning eight of its nine draft picks from last season, after losing seventh-round pick Alex McGough to the Jaguars early in the offseason. The Seahawks are also bringing back defensive tackle Poona Ford, who went undrafted but ended up being one of Seattle’s best defensive players.

The 2019 Seahawks hinge on how these nine players perform in their critical second NFL season. With growth across the board, Seattle could easily find itself back in the playoff picture with another 10-win season.

Here’s a look at each of those players, how each performed last year and what can be expected from them in 2019.
