Jeter has by far and away the worst UZR of any full time shortstop of all time.
Ricky Guit and Chris Gomez are with him, but they were not full time shortstops their entire careers.
Jeter probably should have played his entire career at second base. Like Bernie Williams, his defense was horrendous for his position, but his bat was amazing for the position they played.
Bernie could have played left, and Jeter second (but they didn't have anybody better to play either position any way) but their bats would have been less valuable out of those positions as well. These are Yankees teams that had a lot of production from a lot of positions, so moving their bats down the defensive spectrum wouldn't have really mattered.
But Jeter has been pretty bad defensively most of his career, and not by just UZR. By every defensive metric. It used to be the most common baseball argument along with Howard and RBI's for the last three years or so, but I haven't seen a Jeter defense argument in awhile.
To those that do not know mathematics it is difficult to get across a feeling as to the beauty, the deepest beauty of baseball. If you want to learn about baseball, to appreciate baseball, it is necessary to understand the language she speaks.
