On November 28, it was announced that Geno Smith would start against the Oakland Raiders in Week 13, which snapped Eli Manning's 210 consecutive games started streak, the longest active streak in the NFL at the time. It started controversy, with present and former teammates, opponents, fans, executives, and television and radio show hosts coming to Manning's defense. The benching of Manning also led to speculation he would possibly join the Jacksonville Jaguars, which would reunite him with former Giants head coach Tom Coughlin, who at the time was Jacksonville's executive vice president of football operations. With the move, the Giants became the last team in the NFL to start an African-American quarterback in at least one game. After losing to the Raiders by a score of 24–17, and with the Giants standing at 2–10, both McAdoo and general manager Jerry Reese were fired, leaving Steve Spagnuolo as the interim head coach and Kevin Abrams as the interim general manager. These were the Giants' first mid-season staff firings since the 1976 season. Manning was then renamed the starter for the Week 14 game against the Cowboys.
A 30–10 loss to the Dallas Cowboys in Week 14 dropped the Giants to 2–11, surpassing the most losses in the Eli Manning era with 10 losses (2004, 2014, and 2015). With a 34-29 loss to the Philadelphia Eagles in Week 15, the Giants tied their single season loss record with 12, and after a 23–0 loss to the Arizona Cardinals in Week 16, the Giants fell to 2–13, setting a new record for most losses in a single season in franchise history, eclipsing the previous record of 12, which had been done six times in franchise history: 1966, 1974, 1980, 1983, 2003 and later in 2019, and the worst under a 16-game schedule format. In their last game, the Giants defeated the Washington Redskins to ultimately finish the season at 3–13.
The Giants' 3–13 record was their worst record in a 16-game season in franchise history, their worst winning percentage since 1974, the worst record in the Eli Manning era, their worst record since 2003, finished last place in the NFC East for the first time since 2003, and second-worst in the league behind the Cleveland Browns. The Giants also went 1–11 against the NFC in 2017 and 1–5 against the NFC East. In the process, the Giants acquired the second pick of the 2018 NFL Draft.
On December 29, 2017, Dave Gettleman was hired as the new general manager for the team. Gettleman quickly address the offensive line issues which led to the release of offensive tackle Bobby Hart and the benching of 2015 1st rounderEreck Flowers. Flowers started all games to this point being the only consistent starter on the offensive line.
The Giants' original fourth-round selection was moved to the back of the fourth round, after all of the compensatory selections, but no more than 12 picks after where their pick would have been positioned, as part of the punishment for illegal use of a walkie-talkie on their sideline during week 14 of the 2016 season.
Odell Beckham Jr. was declared out before the game due to his ankle injury. The loss of Beckham was too steep for the Giants to overcome who barely mustered 200 yards. The Cowboys set the pace early and were on the field for 47 plays in the first half. The loss dropped the Giants to 0–1. They fell to 1–9 in Week 1 games against the Cowboys, with their only win coming in 2016.

This game was the first time the Giants played an intraconference game on CBS since the 1993 season finale against the Dallas Cowboys (before Fox took over the NFC contract in the 1994 season). The Giants defense played well in the first half, aided by an NFL record 10-play goal line stand, but unraveled in the second half as they tired out.

Despite their miscues, the Giants dominated on offense going for just under 500 yards and Eli Manning had his best performance this season.
