I just don't get the thinking behind "they all suck and there's no better options."
Then play the less ****** option? Why is it okay to play the absolute worst option you have 20 minutes a night on the top pair?
McDonagh - Holden
Staal - Clendening
Skjei - Girardi/Klein
Those are the best D pairings you can create out of the garbage currently on the team. I'm willing to give Girardi a chance on the 3rd pair since he was at least passable when he was paired with Skjei back in October getting 16 minutes a night. Clendening compliments Staal in that he can at least move the puck even if he may be deficient in his own zone and he brings a better presence on PP2 than Skjei. You don't want Holden on the top pair obviously but he's looked really good the past month and a half and he's the best option over Klein and Girardi.
I refuse to accept the fact that the RD on this team blow as a reason to play Girardi 20 minutes a night. There's no fix all solution currently on the roster but that doesn't mean you consistently deploy the worst pairings and personnel you have. Find a way to mitigate how ****** they are.
Why do you believe AV doesn't do what you suggest? My guess is that he understands how bad Girardi is but still believes he is a better option than Clendening. I have no idea if he's right, but he sees these guys a lot more than we do.
I also believe that if management agrees with you, it's up to them to issue an ultimatum to AV. Change it around or you're gone.
