The article author provides the following quote:
It would be tough for the Yankees to argue against giving Jeter a six-year extension.
And so I says to myself: Boy. Do I know some folks who could get some fuel offa that line.
In Heyman's SI article on which the post is based, it mentions A-Rod and how 6 more years of Jeets brings him to age 42, which is the same as A-Rod will be at the end of his contract and other congruencies, and it also describes them as "frenemies", so make sure you read that, too.
