Pettitte in perspective

ESPN's Rob Neyer has a very interesting analysis of the Pettitte move. Since he has all those impressive postseason wins, I'd never really taken the time to look at Pettitte's stats in any kind of depth, but Neyer contends not only that Pettitte is, at best, Houston's third starter, behind Roy Oswalt and Wade Miller, but also that he's not even as good a pitcher as the White Sox' Mark Buehrle, who also signed a three-year deal yesterday, (but, in his case, for a 'mere' $18 million).
