The current d group unit, yup you are correct, but the problem with that is the Jets have yet to ice their best defensive unit.
Until Samberg and Heinola are in the lineup, we are missing 2 of our best dmen. And I would even add Stanley in there, as he outperformed Beaulieu and Demelo when in the lineup as a rookie.
They are getting major ice with the Moose, - Stanley (Taxi Squad) and the game plan is to get their feet under them in the AHL, then promote to the Jets when they look solid.
After a few games in the A, its clear that both are ready to be NHL dmen.
