His FIP this year is 3.56, just ahead of names like Sabathia and Cain, and just behind names like Greinke, Santana, and Price. I get that FIP measures all sorts of things that ERA doesn't reflect, but it's still weird to me to say that Wells has been "great." It's mostly semantics, I understand. I'd be fine with saying his peripherals are good, but the results have been mediocre. His WHIP is 1.40. That's not great. If you buy into the sabermetric principles at work here, you'd conclude that the mediocre results were largely out of Wells' control. That said, I agree with you. Great tends to imply dominant, and he hasn't been that. What he's been is effective.
