What list? The guy doesn't have a contract.
If I recall correctly the Oilers attempted to acquire Filpulla at the trade deadline the year they made the playoffs and he wouldn't waive his NTC. So if he wasn't willing to come to Edmonton when we were a playoff team on the rise it could make some sense he might not be willing to come now that we're a trash heap.
I can't actually find a link backing this info up though. But this is what I seem to recall.
And of course things can change. Maybe Filppula has a relationship with Holland that he didn't have with Chia. Sort of like Lucic and Chiarelli.... rip
