Without hits, I would drop Landy for Tlusty.
And I don't think it's Landy faltering so much as finding form after a concussion.
Out a curiosity, who else is an FA? - your league has 6 teams, so I imagine there's a wealth of players out there.
Oh, and I'd drop Ladd before Wheeler. Wheeler is a notoriously slow starter, but I see him producing ppg.
