Doesn't seem we're that far from 20, but we have a good ways to go to getting into the mid teens + a good Major League team. Other teams down with us have substantially better Major League teams (Oakland, Tampa, Detroit, e.g.). Seems like we lack real high end prospects.
The Astros should be the top farm - high picks and they appear to make the most of them.
Brewers seem like a basket case.
Mets are interesting - #6 without a #1 pick since 2010.
