Their rotation of old f***s has been disastrous:
Quintana - broke before the season even started
Carrasco - kind of broken, and terrible when he's pitched
Verlander - hurt, then replacement level when he's pitched
Scherzer and Senga have both just been about average, and you expect more than that from them
They're paying those 5 starters 128M this year, and they've been worth a combined 1.7 fWAR
