Not too long ago, I wrote a column that was mostly about relievers, mostly about the free agent market, and mostly about how hard it was to spot any actual, meaningful upgrades to the bullpen which were easily available for the Cards to sign, despite a whole lot of people seemingly convinced the Cardinals need to make a bunch more additions to the club. It was also a column that lacked any solid answers, any grand, overarching narrative conclusions, because building a bullpen in modern baseball is a confounding exercise at pretty much all times, it seems.
