The Seattle Seahawks need to get a win in Week 1. Sure, the season isn't over if they don't beat the San Francisco 49ers, but getting a victory against an NFC West rival would be a great way to begin the season. One never knows if the outcome of Week 1 might be important in Week 18.
Seattle shed itself of a couple of outspoken players this offseason, and the culture of the team appears to be more poised and professional. DK Metcalf isn't around anymore to get mouthy with opponents on the field. Cooper Kupp seems less likely to do that.
