The New York Giants are open to trading down from the No. 2 overall slot in the 2018 NFL Draft.
The Giants believe Manning has several years remaining in his career.
"Are we open for business? You know, whatever," said Dave Gettleman. "Any decision I make is going to be in the best interest of the New York Football Giants. Plain and simple. So if someone makes me an offer I can't refuse, would I move back? Depends on who is there.
"Again, if there is a guy worthy of being the second pick of the draft and what we're basically saying and answering that question to the affirmative, you're drafting what you think is going to be a Hall of Fame player. So you can't get too cute about that thing."
The Browns could select a quarterback first overall, while the Broncos and Jets also have interest in a quarterback.
"It's an interesting class. All shapes, sizes. All flavors," Gettleman said. "It's like Howard Johnson's back in the day. I'm excited about meeting some of these guys here. It will be fun. Obviously we'll be busy once the combine is over visiting and you have your 30 private visits. So that will be part of the process. It's a really interesting, eclectic group."
