I'll rank mine.
1. Cubs
2. Pittsburgh
3. Huston
4. Yankees
I'm impressed with the Yankees and think they have done better all things considered (Prado trade, and then flipping for Evoldi, getting Didi). However their bad contacts sunk them for me. Otherwise I would have them ahead of the Astros who just tanked to get where they are but some credit has to be given to their drafting and they sign UFA to good deals overall. Being in Texas helps but can't fault a front office for location.
Both the Pirates and Cubs have good young talent (more so Cubs obviously) and a overall solid group of players signed or traded for (Arrieta and Cerveli).
