Look, I know you guys aren't used to losing, but there's no way they don't turn this around if everyone's healthy. The question is, can they turn it around ENOUGH. They should comfortably make the playoffs. The only really worrying thing about the results so far is that the teams you've dropped games to are all division rivals.
What would concern me if i were you is that you have huge question marks over two of your starters, one of injury and the other of just plain sucking, plus your bullpen isn't looking too hot (tbf ours looks little better right now,) and you're very short of trading chips.
Even if, say, Brown gets healthy or Wright rediscovers his Atlanta form, and you manage to trade for another good bullpen arm and a starter to cover/replace the other, you'll still be in the position where a single injury to either Pavano, Johnson or one of the top two-thirds of your lineup happens, you're screwed.
