This is old news and has already completely cooled down. I think it's a great idea but unless Theo is willing to give up three pitching prospects(think Buchholz, Hagadone, and Bowden) and Lowrie or two pitching prospects(think Buchholz and another extremely highly placed prosepect) plus Ellsbury, then it's not going to happen. Personally, I would send the three prospects and Lowrie and see if you could get away with only giving up one of these three prospects, Buchholz, Masterson, and Bowden. Hanley Ramirez is going to be the best player in the game for a decde to come. His bat added to this lineup would be infinitely more explosive long term than if Texiera had signed here.
But Theo thinks his pitching prospects are gold and is extremely reluctant to trade them away. That's great but at some point the SS and Catcher positions are going to need to be addressed and let's not forget that this team is also stacked in pitching at the major league level with as much as seven All Star level, under 30 arms in Papelbon, Ramirez, Delcarmen, Lester, Matzusaka, Masterson and Beckett. There's only so much young talent that can make it to the majors before having to make room for the talent in the minors or deal it.
I say recontact the Marlins and find a way to get Ramirez back in the fold.
