The difference is there's a new IF coordinator, Story is a very good SS, Kiké won't be at SS, Rafaela/Abreu/O'Neilll are solid OFers that weren't on last year's opening day squad. Guys around the Braves (Ron Washington, Chipper Jones) have said that Grissom was solid at 2b and should be good there given time. It doesn't fix 3B. Maybe 1B is a little better with coaching? The catching is what it is. I think there is hope that the defense is better than what it was the first half of last season.
