Would you sign Derek Jeter to play for the Mets? To my surprise, the responses were overwhelmingly negative. By a margin of 76% to 23%, respondents voted no.[2]

I would most certainly sign Jeter if he was willing to play second base rather than shortstop. The real question, as far as I'm concerned, is "how much would you be willing to pay him?" I imagine that most of the people that voted "no" in the above poll did so because they took ancillary factors into account, such as price.
As far as I can tell, the question breaks down into two parts. One, what is Jeter's on-field value likely to be? And two, what is his off-the-field value to the Mets?
