I am not sure there would be significant difference had I used Bill James, Marcel, Oliver, or Steamer. I decided to choose one before I looked at the data. Otherwise, I might pick the one that happens to have Dozier lower and some of the others higher to better attain the results I expected. Dozier's OPS projections range from 646 to 672. ZIPS had him at 649. Willingham's were 816 to 833. ZIPS had him at 822. ZIPS was least favorable to Doumit and Morneau. I don't think the results would be significantly different had I chosen different projections. The projections seem low, but three of those players are in the decline phase of their careers with some injury history.
