There is a HUGE area between these two statements. Longshot prospects are prospects who are drafted and never make the majors. Not-top-echelon prospects are simply those who are good enough to make the majors but not necessarily the most highly touted. I am fine if Ellsbury and Pedroia turn into above average major league players who stay healthy and productive. This team doesn't need Mickey Mantle in CF, they need someone who gets on and puts up consistently productive ABs.
Your standards for opening the door to prospects is too high a700. You won't talk about a 2B if he isn't Chase Utley, when Utley is once in a generation. I understand not taking anyone off the table in terms of trade talk, and your hesitance to hold onto a guy like Buchholz or Ellsbury when offered a legitimate Major Leaguer. I don't understand your lack of a gray area in terms of what a productive prospect is worth and what they can offer your team. You dis Youkilis, you dis Pedroia and you're dissing Ellsbury even though very strong arguments could be made that all three are highly productive players given their positions and strengths. These are above average players who are making the most of their tools. When players come up who have better tools (young guys like Lars Anderson) I expect the philosophy of OBP and patience will have stuck, and the power will remain. This farm system is promoting and producing a certain type of hitter. I think we can expect that to continue with someone like Ellsbury.
