He had 12 completions on 25 attempts for 87 yards, 0 touchdowns, and an interception in his debut start against the New Orleans Saints.
In a Week 9 game against Detroit, Hundley threw for 245 yards and a rushing touchdown. In a win over Chicago, he completed 18 of 25 passes for 212 yards, no interceptions, and his first 100+ passer rating as a starter.
Hundley had only 84 throwing yards and an interception in Week 13 against the Tampa Bay Buccaneers, while he carried for 66 yards, with the Packers combining for 199 rushing yards and won 26–20 in overtime.
Hundley had 172 passing yards, one touchdown, and two interceptions in the season’s final game against the Detroit Lions. Hundley had a total of 1,836 passing yards, nine touchdowns, 12 interceptions, 270 running yards, and two rushing touchdowns in the 2017 season. He was traded to the Seattle Seahawks in August 2018 for a sixth-round pick in the 2019 NFL Draft.
