A broken offensive line that can't protect the passer. A anemic running game that can't crack four yards per carry. A punt-return team that gives up a touchdown at exactly the wrong moment. And, of course, a quarterback that looks like he is 36 going on 56 after another dismal performance.

Don't Edit

The Giants look like a bad football team after their 24-10 loss to the Detroit Lions. They are 0-2, and while that is a record shared by their great Super Bowl team 10 years ago, only 12 percent of teams that lose their first two games in the NFL make the playoffs. For a team that expected great things, this is a humbling start.

Can this team recover? We'll find out in six days when it travels to Philadelphia to play an Eagles team that has won five out of six in the series. It'll take a complete makeover on offense, because right now, that unit looks broken -- and the grades in the Week 2 report card reflect that. Here they are:

ELI MANNING

Don't Edit

Here is the play that sticks out: Manning, running for his life (again) after Ereck Flowers misses a block, falling to the turf without a Lions player even touching him. A good quarterback makes a play there, like Matthew Stafford did in this game with his feet on several occasions. A good quarterback also doesn't throw behind Evan Engram for that killer first-half interception. Manning, to be blunt, has not been a good quarterback this season. It's time to stop making excuses for him. GRADE: D.

RUNNING BACKS

Is Shane Vereen, who was supposed to be a third-down option, the best running back on this team? None of the players at this position has shown any ability to gain yards behind a bad offensive line, but Paul Perkins (seven carries for 10 yards) needs to head to the bench after a second-straight poor performance. GRADE: D.

WIDE RECEIVERS

Hey, look who was back. Odell Beckham Jr. played for the first time this season and was a nonfactor, catching four passes for 36 yards. Head coach Ben McAdoo said that he was "limited" in his return from an ankle injury, which begs the question: Why play him at all? Meanwhile, free agent acquisition Brandon Marshall dropped a perfect Manning throw for what would have been a huge gain. Oh, and rookie tight end Evan Engram punctuated his first NFL touchdown catch with a 15-yard penalty for grabbing his crotch. Ugly. GRADE: D.

OFFENSIVE LINE

Don't Edit

It is hard to quantify just how big a mess this line has been through two games. Left tackle Ereck Flowers has already given up four sacks this season, and the poor blocking has contributed to the team's inability to run the ball. Head coach Ben McAdoo has to make changes, but he might be hamstrung by the personnel. That's on GM Jerry Reese. GRADE: F.

DEFENSIVE LINE

Jason Pierre-Paul had a strip sack of Stafford that could have given the Giants a much-needed boost -- had Manning not just thrown that gift away on the next play. Overall, though, the Giants expect much more out of a unit that dominated at times last season. Detroit rushed 32 times for 138 yards. Not good enough. GRADE: C.

LINEBACKERS

The unexpected absence of B.J. Goodson, who was inactive with a shin injury one week after an impressive 18-tackle performance against Dallas, paved the way for undrafted rookie Calvin Munson to get his first shot as a started. Munson handled the spot duty as well as could be expected, with eight tackles. The defense isn't the problem here. GRADE: B.

SECONDARY

Cornerback Eli Apple's coverage on Marvin Jones Jr. was good, but the Detroit receiver still turned in time to make a perfect catch on a 27-yard touchdown pass. Stafford had just 122 yards passing, so the secondary -- even with Janoris Jenkins on the bench with an ankle injury -- wasn't the problem here. GRADE: B.

SPECIAL TEAMS

Don't Edit

The 88-yard Jamal Agnew punt return for a touchdown was an absolute back breaker for this team, an unacceptable play that gave the Lions a two touchdown lead. Lions kicker Matt Prater hit a 56-yard field goal at the end of the first half that bounced off the cross bar and barely sneaked behind the uprights, one of those unlucky breaks that makes you wonder if this is just not the Giants season. GRADE: F.

COACHING

John Munson | NJ Advance Media

Well, what's it going to be, Ben McAdoo? He went 11-5 in his first season as head coach on the back of an elite defense, but now an offense that was mediocre, at best, in 2016 looks completely nonfunctional. McAdoo has a week to turn this around or it could be a long season of listening to the boo birds at MetLife Stadium. GRADE: F.

OVERALL

Giants fans will hold onto that memory of the 0-2 start leading to a Lombardi Trophy in 2007, but it's hard to imagine this team making the playoffs if it doesn't dramatically improve on offense. Can that happen? The NFL is an unpredictable league, but there were so few signs that it will against the Lions. That defense, however, offers a glimmer of hope after holding a second opponent below 20 points. GRADE: D-minus.

The Giants have lost five of their last six games against their hated NFC East rivals, who dropped a tight game in Week 2 at Kansas City. Carson Wentz completed 25 of 46 passes against the Chiefs, but it wasn't enough to overcome a pair of killer Philadelphia turnovers. This game will not only help set the early-season NFC East standings but provide a good measuring stick for this Giants offense.
