As the legendary Yankee Yogi Berra used to say, "You can look it up".
Look up on baseballreference.com and look at transactions from those years 1955-1964 and see how many times the Yankees used older players and cash to get the A's younger players like Roger Maris and others to help their team to a championship. Players like Hank Bauer were traded with money for younger players. I remember Ralph Terry, Johnny Blanchard, and Bob Grim changing hands.
All you have to do is look at the Cleveland Indian teams from the 1970's and look at how Graig Nettles, Richard Tidrow, and Chris Chambliss were some of the cornerstones of the Yankee World Series teams. I know you will say that the Yankees management "fleeced" the Tribe management which is true but what sticks Tribe fans in the ribs is that it was Gabe Paul who was the Yankees GM at the time. If I am not mistaken Phil Seghi was the Tribe's GM.
What I really want to know is why can't "Yankee Fans" act more like Derek Jeter? Derek Jeter is everything that is right about baseball right now. Jeter has done everything the right way and has EARNED all that he has accomplished where A-Rod has had a little bit of a different road than Derek.
I have been a baseball fan all of my life and "Yankee" fans can be the most obnoxious people I have ever been arround. Back in the 1980's I took my nephew to a Sunday afternoon game between the Tribe and Yankees and the Tribe was playing well at the time but ended up losing to the Yankees 14-0 that day. We sat in the 3rd base box seats with a bunch of Yankee fans who came in on an excursion. Those Yankee fans were the most obnoxious fans I have ever encountered. My nephew was all of about 7 or 8 years old and just loved his team, the Cleveland Indians. Tom Candiotti hurt his elbow in the very 1st inning and the Tribe had to bring in a long relief pitcher named Rich "Not" Yett and of course he got lit up. The Yankee fans were terrible and of course had to taunt my nephew.
The only saving grace was a short small Yankee fan about 70 years old and he talked to my nephew a lot that day. He also talked to me quite a bit that day and we talked about baseball and even though we lost 14-0 that day I had a great time. Why can't Yankee fans act more like that man did than be the smack talking wise guys they almost always are?
Does this explain anything to you at all "SteadyEddie"?
