Kovalchuk has been on the ice for 28 goals against this season, good enough to lead all NHL forwards.
Kovalchuk's plus/minus on the ice per 60 minutes is -2.42. Yet his plus/minus off the ice per 60 minutes is only -0.30. That's the best +/- off the ice for all Devils!
Langenbrunner has a team-worst GA ON/60 of 4.74, almost an entire goal worse than the next-worse guy (Kovalchuk at 3.77). So it seems Jamie's defensive abilities have gotten even worse than Kovalchuk's.
It is interesting to note however team shooting percentage is highest when Jamie is on the ice at 7.69%, though still pretty depressing.
