Anyway, a .725 OPS would put him a shade below avg. at his position.  After so many bad years, it's hard to think his great two months last year (he was awful before that) are going to continue.  But his plate discipline has improved steadily for several years now, so I see no reason to think he'll collapse back to 2005-06 levels.

One reason for optimism:  Jack is clearly a player whose focus comes and goes.  His 2004 breakout actually started in late 2003 after the Pirates got rid of several veterans who'd been making life very hard for him.  His huge two months in 2007 started when it appeared he'd be traded away from a very bad relationship with a very bad manager (not to mention a meddling pitching coach).  With Tracy gone, it's possible Jack will stay better focused and do something like 2004 with more walks.  I may have underrated him.
