Preller definitely got a long leash after the first false start but I don't think you can rip him too hard for building the second-best team in the NL last season, and what has been the third-best team for much of the current season. The recent swoon has also come without Tatis Jr.
The question is will the Giants pass them by as the second-best team in the West longer-term? And will the Dodgers ever slip? It's basically the Blue Jays' longstanding predicament in the AL East. Except San Diego should probably be the Tampa of that division.
