The Rangers can probably tolerate one blueliner playing poorly until they finally decide to amend their blueline closer to the trade deadline, a time when cap space is likely to be plentiful and when the typical NYC obsession with acquiring a big name will take over Jeff Gorton. What they cannot afford is to have multiple liabilities on the back end, particularly on a unit that cannot move the puck as it is and on a unit, that is seemingly playing worse in its own zone as the season progresses.
Kevin Klein has truly come back down to earth and is nowhere near the player the Rangers have enjoyed over the past couple of seasons.
