First of all, run prevention is a totally valid strategy that a number of real teams endorse.

robusk is placing emphasis on splits. acecards is valuing speed. babypop values pitch control and quality of pitches.
The 0/0 in amateur scouting is a valid strategy in that it frees up a ton of money for your organization in other means. On average you're getting at least $25m more to spend on players by abandoning the draft.
