EAST RUTHERFORD — The 82,500-seat building was likely not even half filled at kickoff. About half, if not most, of those fans were wearing purple to support the opposing team. And yet that wasn’t even the biggest embarrassment for Giants co-owner John Mara. Two hours before kickoff, a plane with a banner was flown above MetLife Stadium for the second straight carrying a damning message. “MR MARA ENOUGH — WE WON’T STOP UNTIL YOU FIRE EVERYONE,” the banner read. The Giants lost again on Sunday, 35-14, which was no surprise because they were playing the Super Bowl-contending Ravens. But their mostly noncompetitive spirit is jarring. They fell into a 21-7 halftime hole to move past the 2008 Lions, who went 0-16, for the worst first-half point differential at home (-96) in a single season since 2000. “Just control what we can control,” head coach Brian Daboll said repeatedly when asked about the plane. It’s clear the third-year head coach isn’t interested in publicly defending his job security as Joe Judge once did before getting canned in 2021, but the results make it hard to justify bringing Daboll back for a fourth season. The Giants have lost eight home games for the first time in their 100 years as a franchise, and they have tied their record with nine straight losses overall — a feat matched only by the 1976 and 2019 teams. Moreover, they are one loss away from becoming the first team to go 0-9 at home since the NFL moved to 17-game schedules in 2021. They’ve gone winless at home only one other year in team history (0-7 in 1974). It remains unknown who paid for Sunday’s pregame plane — conceivably the same party that organized the one last Sunday that implored Mara to “fix this dumpster fire” — but the bottom line is that fans have every right to be disgusted by this historic futility. The Giants have never averaged fewer points per game (14.8) in a season with at least 16 games, and yet their special teams might even be worse. The kick return unit started Sunday’s game by allowing a 59-yard return, and then later in the first quarter the punt return unit allowed the Ravens to rip off a 22-yard return. Oh, and up until late in the third quarter, the Giants’ only 20-yard pass play was negated by an illegal shift penalty. It’s just all the little things that likely make fans want to put paper bags over their heads in the stands. “These guys are doing everything they can do,” Daboll said. “Ran into a good football team with a lot of good football players, and they played well and we didn’t play well.” If you’re fishing for a positive, well, at least the Giants’ defense makes a play sometimes. Brian Burns has been a solid addition to New York as the 26-year-old linebacker sacked Lamar Jackson in the first red zone during the fourth quarter to become only the eighth player in NFL history to record at least 7.5 sacks in each of his first six seasons. The game even started off encouragingly when Adoree’ Jackson stripped Lamar Jackson for a fumble on the opening drive, despite the Giants being down their top-three cornerbacks because of injury. It’s hard to fault the Giants’ defense for cracking when the offense rarely scores two touchdowns. At the same time, it’s hard to truly gauge the defense’s performance when the opposition has little motivation to keep its foot on the gas with aggressive play-calling. The losses are simply inevitable at this point. That must make it borderline impossible for even the most diehard of Giants fans to stay invested this season. The quarterback of the future isn’t even on the roster, either. The last four weeks have been a game of musical chairs with injuries and ineptitude, as journeyman Tim Boyle became the Giants’ fourth quarterback this year when Tommy DeVito sustained a concussion in the first half. “It’s a tall task for both coaches and players because each quarterback is so different,” wide receiver Darius Slayton said. “For a coach, you’re trying to call stuff that makes them comfortable, and for us as players, you’re trying to do stuff that makes them comfortable. But in today’s case, Tim gets in and … it’s hard to make those adjustments on the fly, but ultimately it’s what we get paid to do.” Boyle did actually make some nice anticipatory throws in the second half, like on a 23-yard touchdown to Malik Nabers in the fourth quarter. Still, the Giants were trailing by 28 points and Baltimore’s defense was simply going through the motions at that point. And you have to wonder, with all the fan indifference in the form of empty seats and message-sending planes, how much longer Giants ownership can continue going through the motions with this failing coaching staff and front office. “They’re competing,” Daboll said when asked about his players’ mental state. “We’ve got a young (team), a lot of guys in and out. They’re competing. I appreciate the way they’re competing. Just not getting the results.”
