Listen to "My Arms, Your Hearse" and tell me that Lopez wasn't stiff on that record. Lopez relied way too much on his "signature beat" (a double paradiddle, I think it is?) and other various beats and fills to be "not predictable." I could listen to any song he's played, having not heard it before, and predict almost exactly where it was going before he even played it. I'm not trashing the guy, because I loved his drumming, but saying that he wasn't predictable is pretty farfetched for any sort of musician.
