Josefson, 23, had one goal and three points in 27 games last season.
The 20th pick in the 2009 NHL Draft, Josefson has seven goals and 25 points in 118 games over parts of four seasons. He had one assist in six Stanley Cup Playoff games during the Devils' run to the Stanley Cup Final in 2012.
You know what? We've played in some pretty special buildings along this playoff run so far. You start in Detroit, you go to Montreal, you come here … I think it's the first team to beat three Original Six teams to get to the Final if I'm not mistaken. That says how tough the road has been. Those are tough places to win.
