How do you measure a man? How can you compare one man with another unless you've seen them both? I cannot tell about other men who played long ago. I saw Mays. To me, Willie Mays is the greatest who ever played. But he is forty and has had his days – he is tired. San Francisco is all tired. For them it was not easy. For twenty days, they were in a tight pennant race and don't know where they are. Mentally, they were going to be tight. You could see Mays is tired.
