I think he is "available" insofar as:
a) He is not one of our top 3 players (Brady, Stutzle, Sanderson);
b) We do not have many pieces of value;
c) He could potentially return an impact player or be parlayed into two solid players
This is a bad example for many reasons, but let's say Tom Wilson was on a 2yr $5mil deal (edit: or Alex Tuch, for example). That is the type of player we would happily trade Batherson for. Or a good two-way center. Or perhaps a limited goal scoring winger and an inexpensive young D. I don't really see that being likely, though, especially in-season.
I don't think Batherson will get traded but, if he is, it would be in a hockey trade.
