Qb start sit week 9 - Dart or Nix?

I play redraft 1 qb but with Baker but baker is on bye. I’ve had nix on the bench for a couple weeks but should I consider dropping him for dart because of Nix’ difficult matchup. Baker will probably be my uncontested starter for the rest of the year except this week. So should I drop nix to start dart this week or do I just keep nix?
