I think the reason is he did and then his existing leverage relievers evaporated and also rotation and depth injuries have robbed them of further depth. There are no solutions that prevent 'Merryweather misses the first half of the year and Alzolay turns to dust, Almonte, Palencia, and Smyly all have a DL stint in the first 6 weeks, and they get minimal bullpen innings from Assad, Wesneski, or Brown due to rotation injuries' from being a problem. As it stands, Neris has been wild but effective, and Almonte was nearly on the Merryweather track before his injury. Adding that to the existing back end along with the stuff guys who could've but haven't yet broken through(Palencia, Little) with the long relievers/rotation depth they have should be fine, but no pitching staff can just shrug off 4 starters and 5 relievers needing DL stints in a 6 week span.
