Let's not overthink this. It's simple: the team stinks. Expectations were way unrealistic. Best rotation in baseball? We have two reliable starters. Best lineup? The lineup without three of its best four hitters is anemic, and it is doubtful that even two much less three of them will ever all be healthy and in baseball condition at the same time. Bullpen? Those three relievers we added overperformed last season and we're now seeing the real thing.
I've tried to be optimistic, but at this point, I'm losing hope that we can salvage the season. Last night did it for me. After losing the first game of the series I was sure we would kick things into a higher gear and win the next two and be on our way. Instead, we didn't even show up. I think the players may have given up.
Dusty was a (regular season) miracle worker and we'd probably be 16-8 with him despite the weaknesses, but Dave is a mere human.
