While I don't think Robin is a great manager, all of the things people want to blame him for were there before he was hired with many of these players. Mental lapses in the field, mental lapses on the base paths, laziness, lack of "fire", etc have all been with the core group of these players since they got here. To say Robin is to blame for the faults of these players is ridiculous. They've all had these faults since the Sox got them.
Jesus Christ couldn't come in and make this team a disciplined, well oiled machine. It's just not happening with anyone.
