Agree that the team has found some quality relievers, but if you throw enough arms at the proverbial wall, some are going to stick.
The Cubs aren't the only team to take this approach, but they do seem to struggle with it, in some sense.
They consistently pay for past performance with guys nearing the aging cliff and then cling too tightly after the fall. This has become a pattern, now.
If they are going to give long leashes, it should be to young, high-ceiling arms.
