I figured out why the trade was made. Steinbrenner was tired of the who is the best SS in baseball arguements. AROD is playing 3B. Next year Nomar at 2B, Tejada in LF.
Once George realizes that SF has a decent SS he will sign him to and make him a reliever. He will take every SS until the position is devoid of talent.
At that time it will be clear. DJ is the best SS in MLB.
