It's pretty clear that Farrell has lost the clubhouse and that his coaches are incompetent. Based on things I've seen from and read on him, Farrell strikes me as being similar to Scott Skiles in the NBA; he'll get a team to do very well at first, but he has a domineering, overly intense personality that wears thin quickly (especially in baseball, where seasons are marathons) and will lead to him being ousted after a few seasons for poor performance as a result of the team tuning him out.
