Change is in the air.

It is midseason, but not too early to begin investigating who might make sense as the next general manager and coach of the Giants. Jerry Reese and Ben McAdoo remain in their positions, but saddled with a record of 1-7, change could be in the air if this season continues to spiral downward. And so, here’s an early look at some possible candidates:

General Manager

Scott Pioli, assistant GM, Falcons: Was the top personnel man for Bill Belichick in New England from 2002 to 2008. A former Jets personnel guy, he got his big chance running the Chiefs (2009-12). It did not end well for him in Kansas City.

Eliot Wolf, Packers director of football operations: Son of former Packers GM Ron Wolf, an executive the Giants hold in high regard. Eliot Wolf is in his 14th year with the Packers and is just 35 years old.

Eric DeCosta, Ravens assistant general manager: Extremely loyal employee of the Ravens for 22 years and has resisted overtures to leave. Could he resist the Giants?

Dave Gettleman: He is well-known and extremely well-liked in the Giants building based on his relationships built up as an executive with the team from 1998 to 2012. Got his big break as the GM of the Panthers, got them to the Super Bowl but was fired, shockingly, this past July. Age (66) could work against him.

Brian Gaine, Bills vice president of player personnel: Longtime Texans executive with 18 years of NFL experience is in his first year in Buffalo. New York (Pearl River) native, he worked for Bill Parcells with the Jets.

Coaches

Josh McDaniels, Patriots offensive coordinator: Play-caller for Bill Belichick and part of five Super Bowl teams in New England. Hired by the Broncos as 33-year-old rookie head coach but crashed and burned, going 8-8 and 3-9 before getting canned. Says he learned from that sour experience.

Nick Saban, Alabama head coach: The Giants nearly hired him in 1997 before they went with Jim Fassel and remain intrigued, from afar. Ranks with the greatest coaches in college football history and would demand extreme power and money to return to the NFL, where he failed the first time around with the Dolphins. He is 66, no spring chicken.

Jon Gruden, ESPN analyst: Won a Super Bowl with the Buccaneers and always sends out mixed signals about his desire to return to the sideline. He is not exactly what the Giants usually look for in a coach, but you never know.

Sean Payton, Saints head coach: There has been an awakening in New Orleans, but it might be time for a parting of the ways. Payton impressed the Giants as their offensive assistant and coordinator working under Jim Fassel and he is a proven winner who might be able to revitalize Eli Manning.

Teryl Austin, Lions defensive coordinator: Giants came away impressed with him after interviewing him two years ago. Former NFL defensive back is 52 and is ready to take the next step.
