Stop now, John Henry, before you let your emotions about Manny's money and weird behavior, and about Nomar's agent's mouthing off, drive you to do something you don't need to. Right now, without any more moves, other than filling the hole at second, you have the team you need to get into the ALCS. You also have the chemistry, and if you don't think chemistry matters, look at 2003 Patriots, 2002 Angels, 2003 Marlins -- and 2003 Red Sox.
Just because you can doesn't mean you should exact revenge on Manny and Nomar for whatever it is they have done to piss you off. One of the cool things about power is that you don't have to use it to remain powerful; just the threat of using it should be enough for Manny.
And what's with the attitude about Nomar? When has he ever said he wants to leave? He plays and plays hard, and that's about what you should expect from a future HOF shortstop.
