Martinez has been golden for me as well in my points league and Miller has been sneaky-good pickup in my one roto league. In all honestly, I would buyout Kindl and make the move for Miller. I am not sure Martinez will be able to keep this up beyond this season and with blocks being a new category, Miller could really help you out.
Separate questions for you. If I have any fantasy questions, do I simply just tweet them to you?
