Apparently, Francona is out officially. That's the word on mlb.com
I'm hearing Valentine's name in a number of places. He seems a good fit in terms of team needs.
Smart, experienced, disciplined, fundamentals oriented, good with media (a part of the media, actually).
I would suspect the coaching staff will be cleaned out, as well. The new manager should bring in his own people, though the GM has a hand in that, too.
Some of the other guys mentioned don't have the experience to handle the Red Sox clubhouse situation right now. These are a bunch of talented guys who have been given too long a leash--for too long.
Try handling that without prior managing experience in MLB.
