What?
No one is saying anything about Ellsbury's range.
You must be confusing range with a player's ability to read the ball coming off the bat and getting a good break on the ball. That IS a deficiency in his game. That, and of course, his Damonesque (sp) arm.
His tremendous speed, overall athleticism, and a willingness to fling himself perilously at balls enable him to make some spectacular plays.
Overall, as I've said several times on this board, he is a work in progress.
