Yup, if they are going to win the series without Eller (b/c I agree with you, that 'perfection line' was humming after he left), they need someone else to step up and be a difference maker...whether its through offense or defense. That could be Mantha -- like you said, he had some great looks. Or Oshie...Ovi....etc I also really like Orlov's play this series...we need him to continue that. Oh, and stop with the stupid turnovers.
Also - where tf is Backstrom? He's been quiet too.
