This team has two strengths; the bullpen and its defense. The bullpen is weakening due to extreme overuse and defense can only carry a team so far when the offense is no sucking big time.
The bullpen has been throwing way too many innings all season and its now catching up to them. Add that to a lineup with no punch and this was bound to happen.
I think the bullpen is more than good enough especially with Devin on the way back but the offense is not nearly good enough and the starting pitching almost never being capable of going 6 innings has worn down the bullpen.
There is no reason to go all in with a team that is maybe the 5th or 6th best team in the national league. I'd do the unpopular thing and move Adames and Devin if someone wants to overpay for them.
