Honestly, if you really did want to drop someone, it should be Varly. The Avs are a no-go this season. I don't see them shaping up either. I'd personally go for either Holtby or Nabokov. Holby is kind of a tough call. Nabokov, we know how he plays. Holtby has been doing better than he started out as. But I personally think Nabokov will out win him.
Message me about your keeper leagues if you need another player. I'd love to be in a keeper league next season.
