Agree with TT, this roster construct is fine if you're getting production from the entire lineup, but when you have essentially black holes at 2/3 spots in 1B, 3B and DH most days, you're just screwed from the outset.
I 100% agree with the blame being placed on Ross because he's slow to react to what players' performance are telling him, good or bad. That and the bullpen usage is just infuriating. Even yesterday in a win, running Leiter and Alzolay back out the way he did after getting knocked around the day before didn't make a lot of sense to me.
