POJ is still young. I expect him to make some mistakes and have some bad games from time to time.
Ruh, this is who he is. At 33, he's only going to get worse and he's at best a 7D to begin with. The Wings have a solid squad, but if they are able to push him around like this, I shudder to think what a real playoff team would do let alone in a playoff series. On top of that, he's not at all a good fit for POJ. IMO, you either need a better PMD so that pairing becomes another offensive/transition type of pairing or a bigger, tougher, stronger crease clearer type. Ruh's nothing. I know nothing about Shea or Ludvig, but they've at least got some size so maybe they don't get pushed around quite as easily.
Having said all that, $5 POJ is taken out of the lineup before Ruh. Might not be next game, but if there is ever a non-injury related shakeup, you know what Sullivan is gonna do.
