I'm not saying that GMs don't make mistakes. They all have their share of bad moves. Pablo was certainly not a good move, but I still maintain that while expecting some decline was reasonable, anticipating him falling off as much as he did was not. Despite it being a bad contract, almost everyone expected the team to be good enough to make the playoffs.
I didn't like the Price contract, but I have not criticized Dombrowski for Price's performance to date. Price was about as sure a bet to uphold the value of his contract through at least the first 3 years as any pitcher could be. If Price stinks for the next 2 years, that is not Dombrowski's fault. The last 3 years of his contract are a different story.
My point is that we may or may not like some signings, but if the consensus is that the team is the division favorite, then the GM has done his job for that season. If we fail to make the postseason this year, that will not be Dombrowski's fault, regardless of the fact that I am not a fan of his overall philosophy.
