They're a flawed team, but it's hard to see anyone that's better in that division.
What's likely to separate them though is that Kenny Williams is likely to make a big move if necessary. I think he's likeliest to go and bring in another starter, which I think they'll need. And likely to go out and get another bat (Mike Cameron, perhaps?), as well as call up Gordon Beckham. The White Sox seem to have a good trainer/conditioning program which seems to have helped them beat the odds a bit with regards to their older players.
