Until they do it in the majors, they are only prospects. It's the job of the FO to figure out which will make it and which will not. I hate to burst your bubble, but you will never see the day when MDC, Hansen, Bucholz, Bowden, Ellsbury, and Bard are all on the Red Sox roster and performing above average. I'd be happy if two of them become major contributors. I don't get excited about prospects until I start seeing them do it at the big league level.
