New York Giants DTs detail motion, fits behind run defense issues

New York Giants defensive tackles Shelby Harris and D.J. Reader said recent inconsistencies in the run defense stem from pre-snap motion, incomplete fits, and a league-wide shift that has left many interior linemen still refining their techniques against the run.

Harris described how motion changes the defensive picture before the snap.

“Pre-snap motion, really what it does, it can exchange gaps,” Harris told reporters on Tuesday. “It can make it where linebackers have to move, DBs have to have communication, and that’s really the main thing that it does, is it forces communication between defense and it kind of shifts responsibilities.”

He added that the noise at home can complicate those exchanges, though he framed the issue as one of alignment rather than chronic breakdowns.

Reader pointed to specific problems that have produced peaks and valleys this season, including quarterback runs and the plunge play.

“I think sometimes just a little bit of the fits on just some of the stuff, cleaning up that type of thing,” Reader said. “We’ve let some quarterback runs kind of beat us in some places. And that’s always a little bit difficult, especially last week. In a rain game, it was a little bit hard but this week, let a couple quarterback runs beat us.”

The veteran also noted that motion itself can pull a defender’s eyes and alter gap responsibility for a couple of seconds, requiring players to reset and trust their teammates.

Harris placed some of the broader difficulty in the context of how defensive tackle play has changed over his career. The emphasis on pass rush, he said, has produced smaller interior linemen and college schemes that rarely force young players to grind against the run.

“Really in the middle of my career is really more the ascent of Kansas City and opening up the spread so everybody’s worried about rushing the passer,” Harris said. “But then now you saw last year with the Seattle Seahawks, you’re seeing the run make a comeback. You’re seeing this year with Kansas City how Kenneth Walker is now, pretty much almost I think other than one game had 100 yards.”

He called the cycle natural, noting that teams will now emphasize the run more against pass-rush-oriented defensive lines, just as earlier eras required the opposite adjustment.

Reader said the group has shown it can execute the fits cleanly and that the remaining issues come down to discipline and surviving the tough downs that every defense faces.

The Giants will look to tighten those details against a Houston offense that both players described as explosive and capable of attacking in multiple ways.
