That's the wrong way of looking at it.
It's not, or at least shouldn't be, "we pay him like a first line player, so we have to play him there", but "he's a second or third line player, so we have to play him there".
A completely separate issue is why we paid someone who was never intended to be a first line player, top 1C dollars? And by the way, because of how the fool who paid him that structured the contract, it does us no good to buy him out.
Forget about what he is paid. Right now, considering all the other forwards we have, is he better suited to a 1W position or a 2W position or a 3C position?
