Don't count on that Warbler. Yankees are getting too old, Giambi is off the steroids and chances are that Sheffield was on them, but is off now. Bernie Williams is practically washed up. Randy Johnson is how old now...
Last, Steinbrenner hasn't got a very strong minor league system to replace the people.

The Indians, on the other hand, have one of the strongest minor-league systems in the game and were the number 1 team in baseball on ESPN's Power Rankings after the World Series. They have since fallen to 5 (because of free agency), but I don't see that sticking for very long.
