omg you're a masochist! That's a terrible batch of 6 defenceman
and the most god awful matched pairings imaginable. So I guess it would be: well Ferrence has played with Petry lately 1st pairing, awful matched pair. And then what 2nd pairing Nikitin and Fayne, and then 3rd Aulie and Schultz. Guess in this scenario best to play Ferrence with whoever is going to be here long term, so either Petry or Schultz.
But .... I must admit there is a good degree of wisdom in parking Marincin and Klefbom down in OKL and letting them develop as much as possible playing 25 minutes a game, and for the long haul it's not such a bad idea.
Certainly, this season is a right off, but the only concern that immediately comes to mind is what sort of effect this has on the forward group???
Could be mass mutiny by guys we would probably like to keep (Hall, RNH) or need to keep for various other reasons (Yak, Perron), and I'm ambivalent about Eberle long term as he's just too similar to the other forwards, his return on a trade would yield something of value, and I just think a bigger forward would be better on the right side of the top line (and on the PP in front of the net).
But maybe some management of the limited calling up Klefbom and Marincin can keep the troops happy enough as to a potential future, and yet be used judiciously enough so as not to compromise a possible run for the roses (ie McDavid, Eichel)
