Yeah, hang tight and the wins will come. What could you improve? Realistically, unless you can get an AJ green or Roddy white for Nelson somehow, your team is set. Personally I'd wait it out and walk in to another championship. It sounds like you're in a joke of a 10 team league and 10 team leagues are silly to begin with.
