In that case why sack Grifol? A decent manager who nows how to organise a line up, when to go to the bullpen and which reliever to use may have stopped some of those games where they threw away a lead after the 7th inning. And a decent manager who actually inspired some of the players may have stopped some of the veteran players phoning in performances for 90% of the season, and may have got a bit more out of the other less than average players. Maybe I am wrong but certainly in other sports the manager can make a difference, I am not suggesting they would have been competing for postseason but maybe they wouldn't be competing for records of worst seasons.
