I don't think they're comparable. I think people forget that before his endless injury problems during the 11-12 season JVR was playing at close to a PPG rate for the first 20 odd games. He also had flashes of dominance, the 2010-2011 playoffs being the best example, that you'd expect from the 2nd overall pick. Like someone already said, moving for a defenseman wasn't the problem, the problem was that defenseman was Luke Schenn.
Something that bothers me about B.Schenn is I can't quite figure out what he's really good at. He's a subpar faceoff guy, he hovers between average and below average defensively, he attempts a lot of low percentage plays (particularly when entering the offensive zone), and he's just "okay" at distributing the puck. He just looks like a middle of the road 2C to me, but with an incredibly low hockey I.Q.. I expected more from Schenn three seasons in, being that he was touted as the "best player not in the NHL" and was essentially the centerpiece of the Richards/Carter trades.
