I'll also be casting my vote for Comtois. I don't think Zegras is as acclimated to the NHL level yet as he will be, and given his 1st line C duties other teams' top players will be shutting him down a lot more than I think we even expect. Comtois, however, can be dangerous wherever he's used, and is in general harder to pin down.
As for how many? Ehh, 36? I have no faith in our offense.
