I don’t think it’s being considered, but how sweet would that be? Sox get more pitching, and Nomar gets the hell out of Boston where he doesn’t want to be anyway, apparently.
Just fishing for thoughts.
If the Diamondbacks deal Randy Johnson, it will be to free up salary room. No-mah won’t do that for them.
However, don’t discount the idea that RJ could end up in Boston (or elsewhere) for prospects or cash.
Sorry, you’re going to have to peddle your castoffs elsewhere. 
They’re both free agents after this year. Arizona might want to dump salary, but they’d want prospects instead.
With his injury history, and, shall we say, incomplete comeback, who’d want Nomar for *their * stretch drive at that salary?
I don’t know how the salaries of Nomar and RJ compare, but we already know that the Red Sox aren’t willing to spend on the players they really need. If they were, Alex Rodriguez would be playing in Boston.
