I could be a 400 pound dude playing center and there is no way I'd pass up the chance even if my shifts consisted of me hopping over the boards and than having to use the gate back into the bench right after for being winded.
Worried about looking bad? Don't. Nobody's going there to watch you and those that see and recognize you will probably be awfully envious. No matter how badly you stink up the place, you're on the ice with the legends, they're not.
They'll also want to hear all about it so you might not have to buy your own beer for a month or so.
man.. that'd actually be really cool, i'd definitely say go for it
im just happy i got to play ball hockey with tanguay in my high school gym once (he went to my school when he played for the mooseheads along with joey mcdonald and dwight wolfe (who incidentally was part of that malakhov/souray deal))
