Depends, my objective is to be consistently good, year in and year out, and every so often when things go right and the team stays healthy, a WS is in reach. Managing a team for short windows of contention every 10-15 years is less likely to get the prize.
The way to be consistently good is by having a continuing pipeline of prospects hitting the majors. Shatkins has put together a strong player development system.
Who cares if Pearce is signed for 2 and Morales for 3, they are just filler while the rebuild takes place.
