I think the bigger argument to be made is how many players they bought after they were well established. The Phils lineup:
Rollins - Organization
Victorino - Rule 5 Draft
Utley - Organization
Howard - Organization
Werth - Signed to small deal after missing two years with injury
Ibanez - Free Agent Signing
Feliz - Signed to moderate deal
Ruiz - Organization
Ibanez is the only guy who got signed to a big deal like you would see with the Yanks.
jeter - organization
rivera - organization
posada - organization
cano - organization
pettie - organization (and free agent i guess)
chamberlain - organization
hughes - organization
gardner - organization
cabrera - organization
a-rod - traded a bonefied, young all star in soriano to get him, soriano was a yankee farm product
so the catcher, second baseman, shortstop, centerfielder, god-like closer, most of the key figures in the bullpen, and the winning pitcher in game 6 are all yankee farm system products.
and two of their three big time free agent signings from this past year, burnett and texiera, sucked in the world series... as did ole' purple lips.
since 2000 as all sorts of small market, low budget teams made, and even won, the world series, the yankee haters were all "oooooh look see!!! you can't buy a championship, fuckers!!!" and then when they win one again they're all "well of course they won, look how much money they spent... fuckers!!!"
honestly... i know you're pissed, and i feel ya. but the yankees don't break any rules in what they do, and fact is that a significant chunk of the key players on this and every yankee championship team since the mid 90's were home-grown talent.
don't hate the playa, hate the game.
note... i still hate both teams and managed to watch just 5 pitches of the entire world series... but am quite happy the yankees won 'cause all their idiot fans were out celebrating all night while i slept soundly, and they got up late so traffic was non existant and i flew in to work
