The Giants dropped their 10th game of the season on Sunday in Oakland, days after coach Ben McAdoo benched Eli Manning for Geno Smith. Afterwards, McAdoo told reporters that "I'm going to coach this team as long as my key card works. I'm going to coach this team until I'm told I'm not coaching this team."

On Monday, McAdoo was told he's no longer coaching the Giants. He has been fired along with general manager Jerry Reese, confirms CBS Sports NFL Insider Jason La Canfora. NFL.com's Ian Rapoport first reported the news.

Even the senior United States Senator from New York seemed pleased with the development.

Giants president John Mara held a press conference Monday afternoon to discuss the decision.

"[Giants chairman] Steve [Tisch] and I spoke after yesterday's game in Oakland and agreed to talk again today," Mara said, via the team's official website. "This morning, we decided in the best interest of the franchise that we would relieve Jerry and Ben of their duties, effective immediately. This season has been incredibly disappointing for the organization and our fans, and while it would be ideal to make these kinds of decisions at the conclusion of the season, we simply felt now is the time to prepare for a fresh start.

"I have great respect for both Jerry and Ben. Jerry has worked tirelessly for this franchise for 23 years. He has always communicated in a straight forward and honest manner. Ben, as a first time head coach, continued up until this morning to do everything in his power to give us a chance to win. I know the public perception of both these men is not positive, but within these walls, you could not ask for two better professionals."

Tisch added: "This has been an extremely difficult and disappointing season. Unfortunately, there are no easy answers or quick fixes. And John and I were confronted with making the tough decisions of today. We know how frustrated our fans are. They expect more from us and we expect more from ourselves. Our focus now is on developing and improving our football team so that our fans can enjoy the winning team they expect and deserve."

Defensive coordinator Steve Spagnuolo will serve as the interim head coach, and Kevin Abrams, who has been the assistant general manager for 16 years, will be the interim GM.

McAdoo originally joined then-coach Tom Coughlin's staff in 2014 and served as the offensive coordinator for two seasons. He was elevated to head coach in 2016, where he helped the Giants to an 11-5 record and the playoffs. This season, however, was an unmitigated disaster marred by injuries, poor play on both sides of the ball and punctuated by McAdoo's decision less than a week ago to bench Manning.

McAdoo's tenure ends after just 28 regular-season games. He was 13-15 in less than two seasons and 0-1 in the postseason. His dismissal doesn't come as a surprise; on Sunday, ESPN's Chris Mortensen reported that, "McAdoo's handling -- or mismanagement -- of how Eli Manning has been benched has been met with open unhappiness from Giants [CEO] John Mara, who is extremely fond of the two-time Super Bowl MVP."

After Sunday's loss, Manning, who didn't see the field, said he plans to play in 2018 but didn't want to see McAdoo fired. And Smith, who started in place of Manning, told reporters that "...I love Coach Mac, I think we all do."

That's not entirely true; last month, two anonymous Giants players told ESPN's Josina Anderson that the team had quit on McAdoo though defensive backs Dominique Rodgers-Cromartie and Landon Collins disagreed.

"McAdoo has it all," Collins said at the time. "He can lead men. He can do whatever you say. He has the ability to do those things. It's not McAdoo ... it's everybody. Everybody has to look in the mirror, the coaching staff, the coordinators, the players, everybody."

Looking in the mirror started with the general manager and head coach. There will be more changes in the weeks and months that follow.
