This team needs to find pitching, not trade it away. Don't let chicken-and-beergate cloud your judgement of the role Beckett should play for this team next year. Also, no way the Sox would get market value for Beckett. The idea is not logically sound.
Also, how is this team not building from within? Papelbon, Lester, Ellsbury, Pedroia, Bard, Lavarnway, Youkilis, Reddick, Doubront all homegrown with possibly Kalish joining in 2012 and Middlebrooks in 2013.
The problem is not signing FA or making trades, since closing the possibility of exploring outside talent to build a team is (and i don't mean it as an insult, just the honest truth) downright stupid. What needs to happen is a change of how the FO evaluates free agents and how they fit with the team.
