Many of us have been wanting the Pens to make space for prospects to play in the NHL. Eller was the vet that they could move now.
Maybe they could have gotten more for Eller if they'd waited, but that's certainly no guarantee. In the meantime, they've gotten something for him, guaranteed, and they've made room in the roster for at least one prospect to play for at least a few games.
Is this a great move? No, but it's not a bad one either. I mean, the players have already made it clear that they're going nowhere this year, so I see no problem with moving out older players for picks. 2nd vs 3rd rounder isn't all that different in terms of quality, and at least this wasn't Tarnstrom at peak value for Jani Rita and Cory Cross (not that Tarnstrom had much value, even at peak, but draft picks would have had a better chance of turning into something useful than Rita and Cross!)
Mostly, I'm just hoping that this is a sign that the Pens are finally accepting reality and starting a rebuild for real. At least this way, we get a chance to see some more prospects play.
Now go unload more veteran players, and get some more prospects up here. They'll still lose, but at least the prospects are going to try.
