Dave Gettleman walked into the final team meeting of the season, introduced himself to the Giants players and proceeded to tell them this franchise needs to get back to winning. Then he talked about change, which was either a promise or a threat, depending on who was doing the listening.

He also told the Giants not to fear the changes that are about to rain down upon the organization.

“That’s one of the things he talked about, just welcoming that change and that’s what we have to do going forward,’’ receiver Sterling Shepard on Monday as the Giants cleaned out their lockers and parted ways. “Welcome the change, don’t run from it. You never know, you could have a lot of fun with it.’’

That is easier for someone such as Shepard — a youngster who is part of the future — than so many others who will not be back in the building, not after a 3-13 season, a new general manager already in place in Gettleman, a head coach fired last month and a new group of head-coach candidates set to be interviewed, starting this week. Heck, Eli Manning after 14 years with the team does not know if he will be back.

“It’s clear cut that they’re about business, and you got to be about your football and go about certain things a certain way,’’ veteran cornerback Dominique Rodgers-Cromartie said. “I know he’s here to kick ass, I heard that part. I’m all for that.’’

Of course, Rodgers-Cromartie has no idea if he will return, and he is not alone. Gettleman cut Bobby Hart, the erstwhile starting right tackle, one day after taking over, and the roster purge will be swift and deep.

“It’s a new sheriff in town, and he’s gonna run things the way he wants to run things,’’ said linebacker Devon Kennard, an impending free agent, “and ultimately, we’re not any of his guys. He’s gonna want to bring in the players he believes in, who he chooses. Everybody in this locker room he didn’t really choose.’’
