Yaz was in the minors for 6 years and a well known college player. I'd say he was evaluated by many baseball scouts and evaluators for many years. I don't think you'll find anyone who thought he was a swing change and philosophical change from being an impact player at the ML level. You didn't have him ranked in our top 30 prospects. What did you miss?
So if I understand your position, Elias bares no responsibility for quickly evaluating and getting rid of Yaz. So how long does Elias need to have a guy in his organization before he bares some responsibility?
