The New York Giants have officially been warned.

Since Jerry Reese was let go and new hire general manager Dave Gettleman was brought in, very little's been leaked in relation to former players who know the man. On Wednesday, all of that changed in one brief moment.

Former Carolina Panthers running back DeAngelo Williams joined “Boomer and Gio” on WFAN to officially fire a warning shot towards the Jints, as relayed to print by John Healy of New York Daily News.

“He’s your problem now,” Williams said Tuesday on WFAN’s “Boomer and Gio” from radio row in Minneapolis. “That’s exactly what I’d tell them. For the vet players that are there now, be very cautious. Once he gets his guys in there, then he develops that relationship with them, and not developing a relationship with the guys that are already there because he doesn’t know them.”

Williams, 34, was cut by the Panthers (Gettleman) after the 2014 season. Perhaps a degree of bitterness is present for the former Memphis back who felt something for Carolina, the city (and team) that drafted him in the first round of the 2006 NFL Draft.

“When you’re down in that locker room you are family … If I’m friends with you or I’m a family member of yours, when I call you into the office to release you, I handle it in a family member type way,” Williams said.

“When you come into an office somebody handling business, ‘Hey man, you’re gone.’ Like, wait, what? … Nine years. I been here for nine years, I played through injuries … I give everything you possibly can for an organization and the way they let you go is ‘Hey man, you’re out of here.’ They let Steve (Smith) go through a text message.”

If there was any confusion at all (not that there should be), Boomer and Gio made sure Williams relayed a crystal clear message.

“I do not like him,” Williams added on WFAN.

The grumblings out of Carolina were always of this nature surrounding Gettleman.

While the talent evaluating expert accomplished tremendous things under Reese prior to his Carolina days, he was ultimately driven out of the Panthers organization not due to his personnel gathering and team building (which can only be described as good if not great), but due to proper relationships with certain individuals, especially veteran players.

As of right now, he's on firm footing with vet Eli Manning. Gettleman has continued to preach his belief in the two-time Super Bowl champ.
