The Cubs, as currently comprised, are the best team in the division and it isn't close. After that, I see a lot of parity. I'm cherry-picking a little, but here's why I don't fear each of the remaining teams: Cardinals: Playing way over their heads, as has been mentioned too many times to go over them all. You aren't going to get a whole season of a 197 OPS+ from Ryan Ludwick. And despite this massive overperformance, they have the run differential of a 24-22 team. They ran out to 10-4 and 16-10 and are just treading water since, and even that will eventually start to fall back. Astros: 11th in the league in OBP + 7th in SLG = 3rd in runs scored? Not forever it won't. As a team, they are OPSing 127 points better with men on base than with bases empty, and that kind of split won't last. Once it does, their offense will look very average and won't be able to carry a mediocre pitching staff. Reds: They were a dark horse in the sense that they were an average-ish team that could do very well if everything goes well, but it hasn't, so they won't. Volquez is a nice story, but he isn't this good yet. They have a lot of young talent, but none of it looks ready for stardom in the league just yet. They could replace average vets with average youngsters, but they won't suddenly become a 90-win team. And there's this: Team Defensive Efficiency 0.680, 30th in the majors. Their defense is really, really bad. Pittsburgh: Decent offensive outfield, a whole lot of mediocre-to-bad pitching. The only decent pitching they have is left-handed, which is death in this division. And...the Brewers. The Brewers are a lesson in how to build a good-OPS, bad-everything-else team. Their combined Pythagorean record this season and last is two games under .500. How do you have an awesome team-OPS and a decent rotation but still be a sub. 500 team? The Brewers go down almost perfectly through the checklist. Horrible bullpen? Check. Dumb manager? Check. Bad defense? Super-check. I don't think many people (especially Brewers fans and the Cubs fans who fear them) appreciate how awful the Brewers defense is. Last season, the Brewers were 25th in the majors in Defensive Efficiency while the Cubs were 3rd (first in the NL). That was the difference in the division. This season, the Cubs are 2nd (first in the NL) and the Brewers are tied for 21st. When the ball is in play, the Cubs are one of the best in baseball at turning it into an out, the Brewers are one of the worst. Corey Hart and J.J. Hardy are essentially the only two average defenders out of the regulars, the rest are bad or worse.
