But quite seriously, here's the difference:
When Lopez was posting low ISO's, I saw a guy feeling his way.
With Mike Carp, I don't see a guy feeling his way. I see a guy with fully-developed pitcher stalking processes right now. He waits for his pitch, and turns on it, the same way he's going to in 5 years. And the ball still doesn't go anywhere.
I could be wrong. That is my considered assessment of Mr. Carp.
