I prefer Lapierre on the 4th but if he takes another step (or rather if he can consistently play like he has in the past) I'd be fine with him centering the third line and being paid an appropriate amount for the job. I don't think it's too likely that it happens but he does have the potential.
As for Higgins I'm indifferent as to whether he plays on the second or third line - really it depends mostly on who else is on those lines and how they are deployed. I think he'd be a good option to do the spade work for Ryan Kesler and another winger (those two did pretty well with David Booth for much of the season) and he's got the work ethic and all-around ability to line up with some less experienced players and help make sure they are able to at least tread water when things go awry. He's also of course good enough to take on a more defensive assignment and still have the ability to score opportunistic goals.
Really the only assignment I don't like for Higgins is in the top six when he's not the least skilled player on his line - and the only chance that happens is if the Canucks suffer a string of injuries.. or if they overpay players like Higgins, Raymond, Malhotra and Lapierre and their depth suffers as a result.
