HAD one of the best farm systems. Remember, they just traded a ton for Kimbrel recently. And due to this, they have very little above A/A+ ball. Outisde of Benintendi(who projects as a bench player minimum, All-Star at best), neither Moncada, Devers, Espinoza, or Kopech are sure things, as they have a long road to the majors and are at least 2018 arrivals at best (Benintendi likely 2017). And knowing Dombrowski, he'll sell the farm to win now.. ask Detroit Tigers fans.
And as for young players, only Betts and Bogaerts are sure things. Still questions regarding Bradley Jr., Castillo and Swihart/Vazquez. Castillo is close to bust material, after that performance this past season, looking no more than a 4th outfielder at best, with good defense but a disappointing bat. Bradley's numbers are inflated by a strong August.. he was the same disappointing offensive threat that has been sent to the minors multiple times. Swihart's D needs to improvement.. but he'll likely be handed the starting job next season because Vazquez is slow in returning post-TJS.
Bradley and Castillo's performances last season is part of the reason I didn't want them trading Margot.. what happens if Bradley and Castillo bust? Benintendi is 2 years away.. and their farm isn't exactly deep in the high minors.
