Short secondbaseman don't last long and crater fast. Unless one doesn't. Tall pitchers take longer to develop consistent mechanics. But they could be worth it. Unless they're not. Short righthanders don't make good starters. Unless they're Pedro Martinez or Tim Lincecum. Then they do.

edit: access to private medical data seems both necessary for a good stab at this project and the sort of thing that no good players' union would ever permit front office types to share with each other freely.
