The Giants and Jets still are battling four days after a controversial ending to their overtime game.

Giants special teams coordinator Thomas McGaughey said Thursday that Jets rookie Will McDonald was lined up illegally before the snap on last Sunday’s game-turning play — a 35-yard field-goal attempt that Graham Gano pushed left with 24 seconds remaining in regulation.

The missed kick opened the door for the Jets to rally for a 13-10 win, while a flag would’ve allowed the Giants to convert a fourth-and-1 and run out the clock on a 10-7 victory.

The Jets pushed back against McGaughey’s claim.

So, who is right? The play is not a foul, according to a source familiar with the NFL rulebook.

The rule states that a defensive player “must have his entire body outside the snapper’s shoulder pads at the snap.”

McGaughey asserts it should have been a penalty, that McDonald was lined up illegally.

“You can’t cover the center. He was covering the center,” McGaughey said. “If you align within the framework of the center, that’s an illegal formation. Can’t do that. You have to be completely outside the framework of the center.”

The discrepancy is over whether McDonald is lined up within long snapper Casey Kreiter’s shoulder pads or not at the snap.

It might take a Zapruder film to resolve in inches of space.

“I’m not trying to be a turd,” Jets special teams coordinator Brant Boyer said, “but I don’t want to address it.”

To be clear, the dispute is not related to McDonald jumping over the line of scrimmage in an attempt to block the kick.

McDonald’s jump was legal, because he did not use another player as leverage to clear the blockers.

McDonald did not touch the ball, but he might have affected Gano’s line of sight.

“It could have [made an impact],” McGaughey said. “Even though it was an illegal play, it very easily could affect the kick. A 6-foot-6, 260-pound dude jumping in front of you, that could affect the kick.”

NFL teams submit a list of plays for the league to review each week in an effort to assist coaches in teaching proper techniques.

Head coach Brian Daboll was asked before practice if he heard from the league regarding the play in question.

“I’ll keep that private,” Daboll said.

It might end up being the final kick of the season for Gano, who was put on injured reserve Thursday and scheduled for left knee surgery.

“You’d like to have everything perfect, but obviously it wasn’t,” McGaughey said. “It is what it is. You missed the kick, got to move on and make the next one.”
