Jets are hard to predict with a new head coach and d coach...don't think it will be a complete rehash of last season, every coach will see things differently, hough personnel hasn't changed much.
They have a hole at 2C with Monahan gone, but there is some excitement about Brad Lambert's potential. Namestnikov played that role for almost 40 games last year with team success so he might get in there.
There should be a training camp battle between Logan Stanley and Ville Heinola. One contributes to PK and team toughness the other to puck movement and rushes and PP. Dylan Samberg is likely to move up to a bigger role with more minutes. Jets could see some 7 d alignments under Arniel I suspect.
4C could be a competition between Barron, Gustafsson, Kupari.
