Heyman breaks down a trade, fails to understand the relative value of players involved, cashes another paycheck
Even if the Cubs never wanted him to start another game for them, he's still worth a hell of a lot more than Chris Volstad. It's essentially a contract year for Zambrano. He has a 2013 option that vests if he's in the top 4 in the 2012 Cy voting, in which case you'd like him on your team in 2013 anyways. Otherwise he's gone in 10 months. You eat $15 MM of his $18MM salary and all you get in return is Chris Volstad? Holy moly, how much were the Marlins going to pay if the Cubs asked for nothing but salary relief in return? What a crap trade.
The Marlins give up Volstad, whose great promise has seemed to dissipate the past few years to the point where he was an unacceptable 5-13 with a 4.89 ERA for the Marlins in 2011.
