Well if we are looking for snarl and physicality, Leipsic is not as good as Gaunce imo.
We need to be fair to Gaunce and as Stormriders says compare him fairly ie what is his role, who are his line mates, what are his minutes etc? I really worry about waiving Gaunce before he has had say, a dozen games, in an offensive role with more skilled faster line mates.
