Looking back at your post from 8-19 to the (sarcasm intended) so-called baseball guru, while I can see that there would be much greater similarity between two starters from the same team (as opposed to starters from different teams) in terms of defense and ballpark factors, "greater similarity" is NOT total equality. Guru, can you say that Lester and Buchholz pitched the exact same number of road and away games? Can you say that they had the exact same defense composition behind them in equivalent numbers of games? Can you say that each has faced the same opponents equal numbers of times? And so forth. Of course not. One night Buchholz may have Vmart catching, and the next night, Lester might have had Varitek catching. Or MacDonald in LF one night and Nava the next night. Or Buchholz may have two more games against the Orioles while Lester has two more games against the Rays. Similarity is not total sameness.
Now to be fair, I'm not entirely fond of some of the modern stats because they seem to lack an intuitive sense of meaning. That is, raw ERA represents the number of earned runs per 9 innings. What does that ERA+ number represent? I realize (IIRC) that ERA+ is supposed to be an ERA stat with defense issues removed, but what does the number mean? It's not particularly intuitive. Last I noticed, Buchholz' ERA+ was in the 190's. 190 what? At least when someone says that a pitcher has an ERA of 2.36, I instantly know that it means 2.36 runs per 9 innings. I guess that I'd lile an ERA+ like stat if it was measured on the same "runs per 9 innngs" scale as ERA. It would be more intuitive to me, and many other people, I suspect.
