Really, the only bad part of this deal is that you have to trade Greg Maddux. But, when you factor in that it appears that Greg wanted to go to a contender, you realize that a trade needed to happen. Could the Cubs have gotten a better "prospect", that's something we may never know..
Career .260 ave, .295 obp, .634 ops
No matter how you slice and dice that, it's really bad.
If you look at his best year, before he got hurt you're looking at a .288 ave, .330 obp, .710 ops, which is still not good.
Cesar is still young.
Maybe Izturis (who's only 26), has his best offensive numbers ahead of him. It'd take .295 and .350 OBP with a gold glove.
One reason that Izturis could be a decent addition is if you look at the middle infield free agents this coming offseason, it's pretty sad. When Julio Lugo and Luis Castillo are the two best free agent middle infielders, you know there is nothing out there.
Since Hendry is probably going to have to explore trade talks for an outfielder (CF or LF, assuming we don't buck up and pay a ton of money to CLee) and a starter or two (the FA starters aren't that good either, after Zito and Schmidt, who we won't get), it seems unreasonable to expect Hendry to have to make 3-5 trades to field a decent team next year.
Sure, having Izturis and Cedeno up the middle will be a liability offensively, but is it worse than Cedeno and Castillo? No, it's not.
