I like the trade and the signing of Martin. The more (good) white guys on the team the better.
However, I am haunted by the ghosts of Marlins past. We were getting a number 2 or even a number 1 pitcher (Josh Johnson), a number 3-4 pitcher (Buerhle), the best SS in baseball (Reyes and yes he was described this way after his time at the Mets by many writers/fans), and some useful spare parts in Bonifacio and John Buck. All we had to give up was Alvarez, Hechavarria, DeSclafani, Marisnick and Nicolino.
We all know how this turned out. I refer and defer to this excellent article: http://www.bluebirdbanter.com/2014/2/20/5429994/hindsight-is-20-20-was-the-marlins-trade-a-mistake
So, I'm not going to jump on board with this just yet. Not. Just. Yet. Lawrie, Graveman, Sean Nolin and Barreto. We'll see. We will see.
