​The Seattle Seahawks are not tempering expectations for Nick Emmanwori before his sophomore season.Seattle’s social media team posted a dramatic video centered on the second-year safety, opening with a shot of the back of Emmanwori’s No. 3 jersey as three warnings flash across the screen: “You can’t run. You can’t throw. You can’t hide.”AdvertisementAdvertisementAdvertisementAfter a series of his rookie highlights, the video lands its final message: “And that was only year one.”It is promotional material, but it also captures the challenge now facing Emmanwori. His first NFL season established him as one of the most versatile pieces in head coach Mike Macdonald’s defense. His second will show how much further the Seahawks can expand that role after opposing coaches have had an entire offseason to study him.Emmanwori finished his rookie regular season with 81 tackles, 2.5 sacks, nine tackles for loss, 11 passes defensed and one interception in 14 games. The Pro Football Writers of America also selected him to its All-Rookie Team.AdvertisementAdvertisementAdvertisementThose numbers only partially explain why Seattle is presenting him as a player offenses cannot escape.Although officially listed as a safety, Emmanwori moved throughout the Seahawks’ defense. He aligned near the line of scrimmage, operated as a linebacker and handled more conventional assignments in the secondary.Macdonald acknowledged during the season that he had “never really had a player like” Emmanwori. Seattle’s coaching staff consequently built specialized packages around a 6-foot-3, 220-pound defender capable of covering receivers, attacking the backfield or tracking mobile quarterbacks.That flexibility is the real substance behind the team’s “you can’t run, you can’t throw” message. Emmanwori was not merely accumulating tackles from one fixed position. Seattle could change his job from one snap to the next without substituting personnel or clearly revealing the coverage.AdvertisementAdvertisementAdvertisementThe next step is becoming even more consistent while carrying greater expectations. Emmanwori is no longer an unfamiliar rookie whom offenses are encountering for the first time. He is now a player opposing coordinators will identify and account for when building their weekly protection and matchup plans.Emmanwori’s second-year progression will soon move from promotional videos to the practice field.The Seahawks are scheduled to open their public training-camp slate at the Virginia Mason Athletic Center on July 25. Seattle announced nine public practices, followed by its annual Football Fest at Lumen Field on August 8.AdvertisementAdvertisementAdvertisementThe preseason begins one week later. Seattle hosts the Dallas Cowboys on August 15 before visiting the Tennessee Titans on August 23 and Kansas City Chiefs on August 28.Because Emmanwori already established himself as an important defensive player, his preseason snap count may not
