I like the Sheppard/Campbell comparison about as good as the Williams/Skille comparison I heard recently. I just don't like the stylistic comparison when it comes to Williams/Skille and the differing roles Sheppard and Campbell seem to be able to fill at the moment.
I had to look up if Sheppard was even a center and though I'm not against adding him all together I don't see how he could "fill" Campbell's role defensively. Like the people who are so against Boll just simply being on the roster, I think you need to realize that while its nice to have a 4th line that's a "threat" every time they hit the ice, the CBJ at this point, don't "need" that at all as a team. We have depth up front where we are able to throw 3 lines that are quite a threat offensively. Adding to that, IMO there is no way Calvert should not/will not see a regular "top 9" shift in exchange for giving a guy like Bourque or Clarkson more time. To me that would make no sense in any way. With that said, with a 4th line consisting of older/slower guys(Bourque, Clarkson, Cambpell, Boll, even "slow" younger call-ups like Chaput/Anderson) Pihlstrom could be a very interesting and/or good fit with a mix of bigger/stronger guys for around 10 mins a game. I like the "poor mans" Hagelin comparison.
