Seriously though, I think Bobby V or Brad Mills will be managing this team next year, in that order of likeliness. I really just don't see Bobby V leaving. He's a good manager, and I think he'd do well with younger kids (Lavarnway, WMB, Iggy, Ciriaco, Kalish, etc). If he can get Pedroia on his side, this could very well be a playoff team.
Gonzo has had a subpar year, CC played 31 games, and Beckett was out of it all year. This trade only improves us. We'll have money and prospects galore to go get those elite arms that we need so badly. Our offense will be good, not 2011-12 good, but still above average.
