Hi Mike- i was born in 1974, so i definitely did not see Mantle play...but there is something very romantic & compelling about his character and exploits on the field (and some off). have you seen the HBO documentary "Mantle"? it is incredible and (i think) answers some of your questions, from the men & women who were there. they start to dissect & explain why he was looked at as a hero and/or even a God. also, on a similar note, have you ever read & listened to Bob Costas' eulogy for Mantle? it was written by Costas & Billy Crystal the night before the funeral in a hotel room in Dallas. it is simply moving, and helps people of my generation get a glimpse into why he was so worshipped.
