The Giants barely do what the Ravens can’t stop.

Something has to give Sunday when a Giants offense with the second-fewest passing yards in the NFL faces a Ravens defense that has allowed the most passing yards. The smart bet on paper seems to be in favor of former All-Pro cornerbacks Marlon Humphrey and Marcus Peters and veteran safety Chuck Clark getting right against an injury-plagued and unknown receiving corps, but the Giants have defied all the odds during a 4-1 start.

“They have ballhawks in the back end that do a good job of tackling, stripping and punching at the ball,” Giants offensive coordinator Mike Kafka said. “I know maybe the stats don’t show it or whatever, but we’ve got to be prepared for a physical game and … put our best foot forward as far as being fundamentally sound and doing the things we want to do on offense.”

The Ravens have allowed 16 completions of 20 yards or more on the way to 290.2 passing yards allowed per game. It’s been a two-year trend as the Ravens allowed the most explosive passes in the NFL last season, leading to replacing Wink Martindale with Mike McDonald as defensive coordinator.

“Where we’re at right now is not where we want to be,” McDonald said. “I’m not satisfied, but I think we’re on the right trajectory.”

So, the plays are there to be made for David Sills, Richie James, Darius Slayton and Marcus Johnson (a practice squad call-up who led all Giants receivers in snaps played last week), especially if the Ravens see those names and ease up after facing tandems like Stefon Diggs-Gabriel Davis, Ja’Marr Chase-Tee Higgins and Tyreek Hill-Jaylen Waddle during the first five games.

“This league is so tricky because records and statistics can be very misleading,” Johnson said. “We know they have a veteran group that’s very well knit working well together, with All-Pros all over the field. We’re not worried about how many passing yards they’ve given up. They could come in and play the best game of their lives — and we could, as well. We have to win our one-on-one matchups.”

The play-action-pass-heavy Giants have just six completions of 20 yards or more — no other team has fewer than 11 — figured into 171.8 yards per game. Minimal contributions from Wan’Dale Robinson, Kenny Golladay and Kadarius Toney have stifled the numbers, and only Robinson is close to returning from injury.

“If everyone continues to have good weeks of practice,” Kafka said, “we’ll be able to piece together a game plan.”

A hallmark of the Giants’ offense thus far is using different formations and personnel packages from one week to the next based on the opposing defense’s weaknesses. Can an offense that went until the final 45 seconds of the first half without a receiver touching the ball two games ago suddenly start pushing the ball downfield?

“We’re very well capable of it,” Johnson said. “With this revolving door of guys going down with injuries, we’re still trying to figure out what works for us and who’s going to step up. Against Green Bay, we saw a glimpse of it, but that’s one game. In our minds, it’s like, ‘Let’s keep proving it and showing the world.’ More importantly, however we win, is how we win and we’re happy with that.”
