Rutherford did a great job last year of handing out some good contracts out to quality players. And the best thing he did was hire a coach who believed in playing young kids. But the real test will be this summer.
Last summer it was pretty easy as he didn't have to hand out any contracts, and the smartest thing he did (that every Pens fan on HF all *****ed about for most of the summer) was that he didn't trade MAF. Everyone else other than Cullen (which was a stupid easy decision) was already under contract. Thus summer however, he needs to resign Dumoulin, Sheary and Schultz. And then Bonino is a UFA. Those 4 going to cost some serious coin, and whatever Pittsburgh does in the next 2 years (their best chance at winning another cup) is going to be determined largely by those signings. Too much, and they won't have the cap space to fill out the roster. Not enough term (Dumo/Sheary are FAs in 2 years) and they'll walk as free agents in a few years.
So no, he's not at this point. But lets give him 2 years to see how Pittsburgh does over that span - because this is when the real work and the real results will be seen.
