It really doesn't seem to matter how many times people repeat it, this sentiment appears. No they haven't. They have played according to their pythag record, maybe above 1 or 2 games depending on which you use. Individually, there are a handful of players over-performing (Dempster, Theriot, and arguably Soto and Fukudome if you distrust the rookie numbers), but by slim margins overall (not Ludwig margins by any means). There are no players having absurdly disproportionate career years. There are players under-performing as well, namely Lee, Lilly, Hill, and Marquis. It's safe to say that people expected Hill to put up Dempster's numbers, and vice-versa. That doesn't change the bottom line production though. The Cubs are not playing over their heads, certainly not in the way the Cardinals have thus far. The Cubs were almost universally projected as the division winners and were expected to produce big numbers offensively. Is it possible last year's under-performance is influencing this year's perspective? Despite winning the division, last year's team under-performed by many games. That team gave away many wins. It could have been just a few games shy of this year's team offensively.
