I like Darling for H2H leagues this year because CHI has a lot of Sunday games - most in the NHL, I believe.
Sunday is traditionally the "day of rest" for a lot of #1 goalies.
And since H2H matches END on Sunday (usually), that makes having Darling as a critical SIT/START option for H2H, where you may need to play/sit a goalie with regard to the ratio cats: GAA/SV%.
There is good value in that simple strategic move in weekly H2H.
If you don't have significant bench spots though, you may get more benefit from an additional skater.
Here is Chicago's SUNDAY schedule, so you can take a longer look at when the SUNDAY-FACTOR might kick in.
There's EIGHT... count 'em... EIGHT Sundays in a row in Dec/Jan! Pretty nice.
