The thing about projections is none of them are very good. Look at the 2011 and 2012 PECOTA, CAIRO, Marcel, Oliver, and ZiPS projections. I got the final editions for most of them here. https://docs.google.com/file/d/0B5pIzP28qdp-TWNCNWNIVHA1NVk/edit We all know the Orioles and A's outperformed everyone's 2012 projections, but the Red Sox underperformed by just as much. People seem to forget that as many teams underperform their projections, as overperform. There were teams spread all over in 2011 as well (Twins, Tigers, Diamondbacks, Brewers, Rockies, Marlins, Orioles, Phillies, Nationals - all finished 10 games or further from most of these projections.) This is not a knock on people who like to follow prospects, and none of these projections are forecasting beyond the next season, but if they were, I think its safe to say that they would be even more off, to the point where they would be almost totally meaningless. Its for this reason that I think you really have to weigh immediate gains more heavily than future ones. Nevermind what is going on with your own players, there are teams underperforming by 20 games or more every year and creating random windows that nobody can possibly see coming
