Asked if he needed the team to improve this off-season before deciding on his future, Jagr responded honestly.
"Wait and see?" he told NJ.com. "I don't have to see anything. If I come back ... Let's talk if I come back: I feel like they have a good enough team to make the playoffs, maybe with one or two changes."
Jagr signed a one-year, $4 million contract with the Devils last summer and will see his salary increase wherever he ends up.
The two-time Stanley Cup champion, drafted fifth-overall by the Pittsburgh Penguins in 1990, is likely to return for a 20th NHL season and the Devils are hoping to retain his rights.
Jagr, 42, has collected 24 goals and a team-high 40 assists for a team-high 64 points in 79 games with the Devils so far this season.
