Here's the problem with putting all of your eggs in the prospects basket. The following, according to
the Baseball Cube, have been the Red Sox' number one prospects going back as far as 1999:
Dernell Stenson, Steve Lomasney, Seung Song, Hanley Ramirez, Andy Marte, Jacoby Ellsbury, Clay Buchholz, Lars Anderson, Ryan Westmoreland, Casey Kelly, Will Middlebrooks, Xander Bogaerts, Blake Swihart, Yoan Moncada, Andrew Benintendi, Jay Groome, Michael Chavis, Bobby Dalbec, Triston Casas, Jeter Downs and Marcelo Mayer.
Depending on what metric you use, a vast majority of these players are/were busts. I see five All-Stars (two of which came when the players weren't Sox property), a few every day players, but aside from Bogaerts, no one that you would build your team around. Finding good prospects is hard. Getting them to the star level is even more difficult. I really, really hope I'm wrong, but this is a tall order for the MAT trio.
