I think Holtby is going to be a fantastic goalie and have always been of the mindset that Backstrom is one of the more consistent goalies in the NHL (when healthy).
In a keeper I'm not as high on Backstrom, but for one year leagues he's bound to get you a respectable GAA along with a SV% north of 91%. I'll take that every time.
