With your posts you provide so much evidence that you are absolutely incapable objectivity that it is hard to take you seriously.
That perception about the Yankees has very little to do with how many of their players are from their farm system. It has to do with the number of players acquired that were legitimate stars when the Yankees got them. Brown, Johnson, ARod (you got him because you agreed to pony up the dough, so it is a money issue too), Sheff, Giambi, Mussina, and Pavano were all considered top-shelf talent when the Yankees acquired them. Matsui and Wright missed that list due to Wright's injury prone past and the fact that Matsui was a roll of the dice.
For the Sox, only Manny, Curt, Rent, Foulke, and Boomer were in that category when the Sox got them. Clement, Mueller, Wake, Arroyo, Millar, Damon, Ortiz, Miller, and Timlin were all good players but not MLB elite when the Sox put them on the roster.
P.S. The fact that the Yankees have more home grown talent will most likely end next year, and once it changes it will stay that way for quite some time.
