Can someone explain to me why this guy is so popular?  He is perhaps the worst regular shortstop in the league.  In the 4 years since his rookie year, he has posted an OBP over .300 once.  This guy has NO plate discipline (has anyone even tried teaching it to him?) and struck out 5x for every walk in 2008.  And don't even try to tell me his defense wins games; his defense doesn't come close to overcoming his offensive shortcomings.  Throw in the fact that he shows no outward interest or excitement whatsoever and I just don't understand the appeal.  If he had any value at all, I'd trade him tomorrow.  It's even worth exploring picking up someone else's expensive trash to get him out of here (Luis Castillo with the Mets?).  I'm not saying he's a bad guy or a clubhouse cancer, he's just an extremely underperforming and highly overpaid anchor in the middle of the Padres lineup and infield.  This team needs more guys who can put the ball in play in this park, that's not Khalil Greene.  I'd explore any reasonable option to get rid of this guy.
