There was an Anisimov discussion in the GDT for game 5.
My opinion, it isn't that Arty has been bad, rather it seems like that combo just isn't clicking for whatever reason. I expect more from that line, but the errant passes and lost pucks... it has just been bad - the combo, not necessarily what any one individual on that line has been doing.
Arty has been very good in the face off circle.
