I understand the frustration, I hate blowing games too.
With regard to the managing though, I think Farrell actually tries to follow the philosophy of Francona, which is to 'manage the season', and that's why you try to avoid burning out your closer in the first week of the season. Managing our bullpen is going to be tricky with both of our 8th inning guys on the DL, and we're going to see some ugly results.
'We need somebody to step up', as the saying goes.
