As an aggregate, the Cubs offense is actually a bit better than last year's. 7th in the league at 4.6 runs a game versus 9th in the league at 4.39 last year, across the board better BA, OBP, and Slugging. The problem is that it's sooooo inconsistent. 15 games scoring two runs or less out of 35. Houston, the worst scoring team in the league at 3.06 runs per game, has had 17 games of two runs or less out of 34. The second worst scoring team in the league, Pittsburgh, at 3.35 runs per game has had 14 games of two runs or less out of 34. The Padres are the third worst scoring team in the league at 4.29 runs per game, and they've only had 10 games of less than 3 runs out of 34 games. Essentially, while the Cubs aggregate numbers are mediocre, they have been just as likely to put up an offensive no-show as the worst offensive teams in the league. Generally, you'd expect a team's offensive production to graph out like a bell curve with a big hump between 4 and 5 runs and a gradual decline from there. However, if you graphed out the Cub's offensive production, you'd see a giant spike at 2 runs, and then a nearly flat graph from there. The bullpen certainly hasn't helped. The team ERA is up about a half a run, and that can be attributed largely to the bullpen, whose ERA is up a whole point from last year. The starters' ERAs are up about .3 runs.
