Is this a keeper league?
If not then Lindback has no value this year, his GAA and Sv% is too high. Yes he's getting wins but that is only one category.
I DO think Backstrom has better potential than Varlamov any day and the reason being is because Varlamov hasn't really proven himself fit to be a starting goaltender. The only reason he is still a starter in Colorado is becaise Giguere is about ready to retire.
Dubnyk is a very viable option right now, he's young, he's got a young strong team in front of him.
As for right now I would drop Varly and roll Dubnyk. Opposed to my previous post of rolling Backstrom, Dubnyk will get you the most starts and decent numbers.
