The 2016 and 2017 Nationals also had a lot of key players miss a lot of time with injuries. They nonetheless won the division comfortably both years. Dusty Baker has some supernatural ability to keep bench players motivated and performing well. Difo, Goodwin, all sorts of random people contributed positively after Dusty sprinkled some of his magic Dusty dust on them. I have no scientific explanation but this seems to happen everywhere Dusty goes, he is often followed from team to team by the same bench players.
