10 team roto, a well rounded but unspectacular team. Advice?

[sting93]

Hi, this is my second year and I'm not an expert. Just hoping I could get some help with the issues of my team... Just some questions, should I start Dave Roberts or Corey Hart or Victorino? Olsen or Contreras when Garcia is healthy? Thanks!
