Pitching is very important, sure. And the Mets have an outstanding one-through-four rotation and above-average one-through-six bullpen... Scott Schoeneweis blows dead dogs and El Duque is in strict denial that his career is over... but if your problems are your fifth starter and your last guy out of the bullpen, you're doing okay. The pitching is there, yeah.
Defense? Defense is over-rated in a sense.
Having not-terrible defense is very important, of course... but the value of exceptional defense over steady acceptable defense in baseball, man, I think people read desperately too much into exceptional defense.
Over the course of a game... or a week or a month... how many plays are there REALLY out there that an extraordinary defender will be making that an okay-but-unspectacular defender won't make?
Most of the defensive plays out there, man, either any basically-competent defender will get it or even the best player at that position will not get it.
Brian Schneider's decent glove will help the Mets a lot less than his complete inability to hit will hurt them, for example.
I mean, you certainly don't want a whole squad of ridiculously ineffective defenders out there... that's not what I'm saying...
But really great defense doesn't mean anything if you just flat-out can't hit.
Gimmie a guy who is a solid defender with an above-average bat any day over the best fielder at his position who's gonna hit .240... any day of the week.
