Perosnally i like Masterson and Cabrera....and considering Ells injury history and his upcoming free agnecy with Boras as his agent, the OP's original deal is not as outrageous as some are making it....
Value-wise, it is not terrible. The OP's biggest was falling into RS-bash-mode but calling Buchholz a headcase for no reason.
The problem isn't so much the value as the fit. He is suggesting that we sign Bourn to a long-term contract, even though JBJ is one year away. So he wants to spend $14M a year for Bourn and leave JBJ on the bench for 5-6 years?
Even if the only thing he did was Ellsbury for Cabrera, it still doesn't do a lot for us. the value works, but there wouldn't be enough of an upgrade at SS to make up for the loss in CF.
