What an interesting thread! Colby you interchanged the words stuff and velocity. An earlier writer defined stuff as ability to effortlessly throw a baseball (and I assume he meant with velocity). I always, always define stuff as movement on pitches. I am sure, at MLB level, it is better to have a pitcher who throws 89 with movement, than to have a guy that throws 96 with no movement. I guess the perfect pitcher is a guy who throws 96 with movement AND control, ala a Randy Johnson when he is on. Interestingly, I would say Pedro Martinez stuff is not as good as Johnson's, and his velocity is less, but his control is more than the Unit. So, I would rank the needed attributes as stuff (movement), control (ability to use stuff), and velocity - in that order. Even if you get a low velocity guy with great stuff and control, you end up with Greg Maddux. That is ok! The quote from BA, re Weaver, states "His command is so good that his stuff plays better than its raw grades." If that means Weaver has little stuff with great control, then he does not have a high upside in MLB. Maybe in college that will get by, but not against a MLB lineup. But if he has good/great stuff (movement) with great, great control, then he is as rare as hens teeth.
