4 important points people don't consider when looking at the myth of Yankees homegrown players.
1) Pettitte was a homegrown Yankee, but he went to Houston. The Yankees bought him back at an incredibly high price. Other teams part with great players all the time, but they don't have the luxury to buy them back. You can no longer call Pettitte a homegrown Yankee. He's another big-money acquisition.
2) Yes, the Yankees have more homegrown players than any other team. BUT (and this is a really big but), when you sign big name pitchers like Sabathia, Burnett, and Pettite for your rotation, it allows you to experiment with homegrown garbage like Hughes, Coke, and Joba.
When you sign big bats like A-Rod, Texeira, Damon, and Matsui, it allows you to experiment with homegrown garbage like Melky Cabrera, Brett Gardner, and Ramiro Pena.
3) Homegrown Yankees in the postseason starting lineup: Jeter, Posada, Cano, Cabrera
Big money signings from other teams: Damon, Texeira, A-Rod, Matsui, Swisher.
Last night, the Yankes 2, 3, 4, & 5 hitters were all big off-season acquisitions. That's the meat of the lineup!.
Looking at pitching...
Homegrown starting pitchers in postseason rotation: NOBODY!
Big money signings from other teams in postseason rotation: Sabathia, Burnett, and Pettitte
4) Yankees fans like to point to Jeter, Posada, and Rivera as examples of their homegrown talent, but these players all came up 15 years ago. Yes, Jeter and Rivera are great. Posada is highly overrated. And keep in mind that every team brings up talent (especially over a 15 year span), but the other 29 MLB teams don't have the money to keep every homegrown player that shows any sign of talent. Only the Yankees have this luxury.
The bottom line:
The Yankees success is only about money. Yankees fans always brag about their homegrown talent, but it's the biggest myth in baseball. This team runs off its off-season acquisitions. It's not about team chemistry; it's not about heart; it's not about cultivating young talent; it's not about great managing and on-field strategy. It's about piles of money building an all-star team. End of story.
