No offense, but "started and ended with Joe Nathan" seems like the kind of thing a clueless national media figure would say about the Twins bullpens of the 2000s. Before Nathan even came here, the 2002 playoff bullpen had 5 very good pitchers. 2004, 2006, and 2009 probably did too, at least by this criteria. (Be sure to look beyond K/9 which has been increasing league-wide.) 2010, Nathan was hurt yet our pen may have been 6 deep that postseason. Bullpens were largely a strength of the Gardy/Anderson years, and generally did not hold us back in the postseason either (outside of a single-game blow-up by Rincon in 2004, and another by Nathan in 2009). The 2019 and 2020 bullpens may indeed be deeper, although starters are throwing less now too -- successful postseason pens of the 2000s didn't need to be deeper than 5. Also note that, like the Maeda vs Liriano comparison above, the 2020 pen so far has only faced 1 team ranked above 20th in run per game which might be boosting their stats relative to pitchers who faced a more balanced schedule of opponents.
