You seriously don't think that spending the way they do helps them have an edge over everybody else? What other team has been able to make it to the World Series in every decade since the 1920's? "Oh, they hadn't won a World Series since 2000!" So? They also made it in 2001 and 2003. Even in the 80's, which is considered their worst decade they made it in 1981. 17 more titles than the next team? Yeah, outspending everyone hasn't helped them one bit...
Spending gives an edge but good decisions get the edge over spending. One of the reasons we didn't win was b/c we were spending so much and making the wrong decisions.
You are brining up pre 90s? There wasn't a huge gap in spending until probably the early 2000s. The Yanks are the greatest franchise in all of sports and have been consistent winners not b/c of money but b/c they have had good people running the oprganization in most years.
Buying a title is waht Fla '97 or ARi '01 did, the Yanks have a long list of homegrown guys on their team. The Sox in '04 had ONE homegrown regular- THAT is more buying a title than anything the Yanks have done.
