it's also worth noting that randy johnson had a bad back in 2006 that, IIRC, really affected him when he was pitching out of the stretch. he had a LOB% of 61.8 that year, which is insanely low (average is around 70 off the top of my head). in 04 he had a 69.5 LOB%, 05 = 74.1, 07 = 72.6, and 08 = 70.9. 06 was a fluke due to a bad back which he had surgery on. it doesn't bother him any more, it's stupid to look at his 06 as an indicator of future success (or lackthereof). also quoting ERA, saying ERA is a bad stat, and then saying ERA+ is a good stat is kind of weird.
