Remember when the Sox had to give up Bogaerts for a pitcher, then it was Betts, then it was they held onto JBJ and others for too long? I've always been a build from within kind of guy who has stuck with the concept of developing your youth.
But the time is now, those guys are up and in their prime. You pretty much have C/SS/2B/LF/CF/RF locked up for the next 4 years. Now was the time to build around those guys and Moncada/Basabe had no place on this team. Sure, if they are as good as we think they are you could easily find a place for them but you didn't have to and you got SALE for them.
As big of a prospect homer as I am the minor league does provide different avenues to serve your team: Building from within, and trading to fill team needs. It made more sense in the past several years to be more patient with the farm system and to hoard the prospects. But now that we have a playoff caliber team, it made sense to cash in some chips and build around our young talent.
I love this deal.
