The fast ball chart is interesting, but Stras doesn't rely on it exclusively so it really doesn't apply. I personally appreciate how the use hundreds of subjective facotrs in comming out with their rankings,
TRUE Rank is a rankings model that uses hundreds of past amateur scouting reports to rank current players. TRUE Rank examines hundreds of different variables and selects the best indicators. The result is a system that selects players 60% more accurately than the average team.
If their results were remotely accurate, you would think that the Yanks or Sox would have bought the rights to it. My guess is the system perfers college prospects, and scores 'accuracy' based on major league time, not actual production.
