Despite being on Seattle's roster for more than a year, Drew Lock had never taken a snap at his home stadium in a Seahawks uniform until Thursday night. Lock threw a pair of touchdowns passes, the second a 19-yard strike to Jake Bobo late in the third quarter, and the Seahawks beat the Minnesota Vikings 24-13 on Thursday night in the preseason opener for both teams. With starting quarterback Geno Smith serving as a spectator — along with most of the starters for both teams — Lock showed that the Seahawks should feel comfortable about their backup.
