It's not entirely fair to say that Gardy does that. In 02, Everyday Eddie is our closer, our best relief pitchers are probably Romero, Santana and Hawkins. In 03, it's still Eddie but Rincon, Santana and Hawkins are probably the better arms. 04-05, Nathan is probably the best bullpen arm but Rincon is dominating, too. 06, Nathan's clearly the best arm but that's a really good bullpen and Reyes was death to lefties. Same in 07 but Neshek breaks out. 08 it's only Nathan. 09 probably the same but Mijares was a revelation down the stretch. Then you start the post-injury Nathan era where Rauch, Capps and Nathan were all closers at one time or another but the best bullpen arms were probably, at different points, Crain, Guerrier, Perkins and Duensing. So, yeah, Gardy used Nathan to slam the door on games but he's also used some really good pitchers in the 7th and 8th inning and gotten some great things out of guys like Reyes as well. And, while Nathan is great, I'm not convinced that he'd put up his closer numbers if he was pitching as a set up guy.
