If that's the case, we should be able to compare the number of really bad starts Zambrano has compared to other pitchers in some way, and see if it's really out of line. That's a lot more involved than just saying "He had some really bad starts, so let's not count those." 40.5% of Dempster's earned runs allowed came in 6 of his 26 starts 62.7% of Garza's earned runs allowed came in 7 of his 24 starts 50% of Zambrano's earned runs allowed came in 6 of his 24 starts I'm sure if we looked at all the more or less reliable pitchers in the league, you'd see most of them fall into the same "boom or bust" pattern. 10% more in the same number of starts is a huge difference between Demp and Z. and Garza has an ERA a full point lower than Z. I think you reinforced my point. and again, I'm not saying the original statement was true...I'm saying IF its true, its relevant. Also those percentages mean very little (to this particular discussion) as Demp may have surrendered 7 runs in 6 innings and Z 7 runs in 3 innings. Again I'm not arguing the numbers, just the logic. IF it is true, its relevant. Bring on the histogram!
