D.J. Fluker was a bright spot on the Giants’ offensive line and in their locker room during a dark 2017 season, but the Giants now have competition to keep the powerful guard in New York.

Fluker, 26, a punishing run blocker and a former Chargers first-round pick, is drawing significant interest from several NFL teams as he heads toward unrestricted free agency on March 14, according to a source. Several clubs have met with Fluker’s agent already and love what he brings on and off the field.

One would think the Giants would prioritize re-signing Fluker, especially because GM Dave Gettleman is so intent on creating a positive and winning culture -- and Fluker was an impressively positive influence last year in the Giants’ locker room, even when some of his teammates were undermining head coach Ben McAdoo.

The Giants also need better depth in addition to an improved starting five O-line, and Fluker’s departure would compromise at least one of those areas, if not both.
