Well it is a prospect site, they tend to focus on their guys more. Sometimes podcasts do go more in depth into MLB players but remember they don't have a MLB scouting team so the information there is going to be likely what we all have access too. In terms of all their guys being "2nd division starters" I'd argue that more often than not prospects are nothing more than that. Right now they have 4 players projecting to be impactful everyday players, with 3 more having that kind of ceiling. This doesn't mean more guys aren't there, there was a time when Mookie Betts and Xander Bogaerts weren't on anyones top 20 and didn't really have any projections. Projecting prospects is an inexact science.
What I like about Soxprospects is their honesty, you'd expect them to be homers but sometimes they are more cautious with their guys than other organizations. I remember they were more down on Lars Anderson than most others in the industry, and they never projected Owens to be anything more than a #4 maybe #3 starter. I don't think they are any better than BA, BP, or anyone else but the reason I trust them so much is the simple fact that they have more eyes, more often on our guys than anyone else with the obvious caveat of the teams scouts. They are usually pretty fair, and sox fans who like to follow the minors are lucky to have a resource like them.
