I'm talking more about style and presence than accomplishments. Both were/are tall, had/have a good eye for balls and strike, and showed their ability in their first year. .
However, to me it's a dead heat between Ruth and Williams as to who was the greatest hitter ever. In his rookie year, age 21, Williams OPS was freaking 1.049 in 149 games. No way do I put Anthony in their company,--which doesn't trouble me the least little bit. Anthony is still amazing.
