But isn't the bigger issue that Farrell and Wills were given:
Kimbrel, Koji (elite relievers)
Tazawa, Carson Smith, Zeigler (excellent setup)
Ross (L), Hembree, Layne (L), Barnes, Abad (L) (excellent to serviceable mid relief and specialists)
Clay, Kelly (starters displaced into the bullpen)
There was also some drek, but surprisingly limited outside the Farrell-championed Noe Ramirez.
On the whole, using quick and dirty ERA+, all but the following have been close to league average or above average pitchers - Clay, Kelly, Ramirez.
Yet somehow, over the course of the season, Farrell has parleyed this average to plus talent into the results we've seen. I realize that not all payers were available at all times (some due to Farrell burning them out), but dealing with that is basically the whole point in having a competent manager. But it's pretty remarkable that people are making the argument that the bullpen is some kind of historically talent-starved disaster. It's also remarkable that better results couldn't have been coaxed out of that pen.
