gunnarthur, some info. 'Until early 2013, it used to be that another significant difference between the two systems was that each calculated Replacement Level differently. That has since been changed, and both sites now calculate replacement level the same way: This new unified replacement level is now set at 1,000 WAR per 2,430 Major League games, which is the number of wins available in a 162 game season played by 30 teams. Or, an easier way to put it is that our new replacement level is now equal to a .294 winning percentage, which works out to 47.7 wins over a full season. As a result of the differences listed above, rWAR values typically come in lower than fWAR values, meaning a 6 rWAR is more impressive than 6 fWAR. But it’s worth noting that the two systems are more alike than they are different, and that their different calculations should be viewed as a feature, not a bug.' http://www.fangraphs.com/library/war/differences-fwar-rwar/ Also, this year, Fangraphs has pitchers who create infield popups as a skill, so those cosnsitently good at that will have their WAR helped as well.
