Miller & Niemi are both top 10 goalies, IMO.
I don't think you are too bad off.

I'd go with Crawford.
Chicago splits their arena with the Bulls and had a ton of off-night & Sunday games.
Even with a revised/changed schedule, this dual-tenant issue will keep the Hawks with some strange game days.

In other words, if you are in a Daily-Start league, Crawford might have less conflicts than Anderson. I also really like Chicago's defense over Ottawa's... but I do believe Anderson is the better goalie (by skills).

All that said, I'd go Crawford because of team & schedule.
