re: Value Based Drafting, Has anyone tried this before?

I've done this for many years. I was doing it myself years before I ever read anything about it. I really like the system and set up an Excel spreadsheet to make the calculations. I do not however compare each player to the last starter at each position. My theory is with the way I rate players, I never try to end up with a player who isn't in the top half at his position. I compare each player to the mean at his position. Each player gets either a plus or minus score and then I sort all the players out based on this score.
