I'd imagine they'll swap Milano with Mantha. Mantha would be better suited with 2nd line minutes and more opportunity to score, since he was buried as a defensive 3rd liner last year when he has far more talent than that, and Backstrom especially needs someone on his line who is a great possession player like Milano is. Also, I'd be surprised if they keep 3 goalies up over a forward, say Snively for example. Sending down Lindgren (if Shepard beats him out of preseason) might allow for 3 scratches as well, by bringing up Frank and Snively.
