Fair?

Encyclopedia of Fake Fantasy Baseball, I like that title, roflmao. But maybe someone can answer a question I don't understand myself. Harry Rodriguez was 16-9 during the season and was instrumental in getting the Mets to the playoffs. I consider R.J. Bellhorn a better pitcher in all reality I think. But his starting stats look worse than a rookie never will be. In 13 starts he only pitched well in three of them and at one point had an ERA of 15+. He actually pitched well out of the pen. Now someone tell me why?
