If we're assuming health and sanity, Rick Ankiel, Mark Prior, and Kerry Wood would all have to be up there with Pedro, wouldn't they? well, no. ankiel still had massive control problems even when he was sane. and pedro martinez has been far far more healthy than Prior or Wood, so the comparison isn't really fair. and healthy, prime (i would assume that's the case for all-time) pedro is still the better pitcher, I'd bet.
