IF (4/5) - Pretty solid at every position. Chipper Jones played really well last year, but he hasn't played 135 games in a season since 2004. Infante is a quality back-up, but wouldn't supply a lot of power from 3B.
OF (2.5/5) - Fairly average, especially if Francoeur doesn't rebound from a down year. CF is undecided.
SP (2.5/5) - Quite a different look for an Atlanta rotation. Lowe was brought in and Jurrjens showed promise last year. You never know what you'll get with Vazquez. The other two spots are up for grabs, but Kawakami should get one. Hudson could return late and Glavine could still sign.
RP (3.5/5) - If Gonzales if healthy, he is a good closer. Soriano, Carlyle, Bennett, and Acosta can all hold leads. A couple of open spots to fill.
Wildcards: Kawakami, Logan, Anderson
Can they beat the Brewers? Yep.
EDIT: I saw Glavine signed like an hour after I posted this.
[Disclaimer: I do not claim to be an expert on your team. I think it's fun to do this stuff before a season starts and then see how close (or how far off) I was.
