After the Giants dropped to 0-2, The Post’s front page roared “What the Hell Is Wrong With The Giants?’’ This week, the question can be narrowed to this: What the hell is wrong with the Giants’ run defense?

Through three games, the Giants are 32nd — dead last — in the NFL, allowing a ghastly 153.3 rushing yards per game. This is shocking. Virtually the same unit, the same players, proved to be a tough bunch in 2016, allowing only 88.6 rushing yards per game, and even more run-defense dominance was expected this season.

The Eagles came into the weekend with a quarterback, Carson Wentz, as their leading rusher and ended the weekend having put up 193 rushing yards on the Giants.

“We let them get almost 200 yards rushing, and that’s what we do not do,’’ safety Landon Collins said. “We can’t condone that.’’

The main problem? Collins thinks too many defenders are trying to make a play, rather than fulfill their assignment on each play.

“We got to do our job, once we do our job everything will fall together,’’ he said.

Linebacker Jonathan Casillas called the defensive showing “poor, really poor.’’

Maybe the absence of defensive tackle Johnathan Hankins (now with the Colts) hurts worse than anticipated. Perhaps this group thinks too much of itself. Opponents are picking at the wound: Only the 49ers (107) have been run on more often than the Giants, who have faced 102 rushing attempts in three games. The struggles of the offensive line were anticipated. The struggles with the run defense were not.

“We got to do a better job of tackling, we gave up too many yards after the carry or after the catch,’’ Jason Pierre-Paul said.

The defense has plenty to work on, and Ben McAdoo said he will use the more physical Thursday practices to tighten things up.

“We had a rough day [Sunday] defending the run,’’ he said. “We need to be better with our blocking structure, and we need to cut down on the missed tackles. We had some opportunities to tackle better, and it starts with those two things.’’
