That might be put to the test Sunday afternoon when the NFC West rival San Francisco 49ers in the teams’ season opener. The Seahawks finished 10-7 last season, missing the playoffs by one game under rookie head coach Mike Macdonald despite a 3-6 record at home including losses in six of their last seven home games. “We have to win at home point blank, period,” veteran Seahawks defensive lineman Jarran Reed said. Even though he grew up in the state of Washington, wide receiver Cooper Kupp said he never felt comfortable as a visitor at Lumen Field.
