That would be a nice projected infield for the next 5 to 10 years. But I just dont think the Red Sox will have an entire infield or outfield for that matter filled with home grown players. Sure it would be a nice heart warming story and is what all 32 clubs would love have is an entire team of home grown players. But this is the Boston Red Sox who have money to spend on big time free agents and trading for what is projected to be the the latest and greatest with the Yankees who dont seem to quit buying players and makiing moves to be a big market team right under the salary cap, the Sox aint gonna change from big spending and trading for outside the organization players anytime soon.
I would love to see a whole team of home grown guys but realistically i just dont ever see it happening, atleast not for us. Tho the infield you mentioned could be great if the reports of the prospects keep progressing and make it to the bigs, just keep in mind a propect looks good in the minors but they are still propects and havent made it to the show yet injuries do happen and block home grown players. Example: Ryan Kalish
