Pure conjecture on my part, but I am guessing that Reds are trying to move one of big three contracts, Harang, Arroyo or Cordero, first before taking on Rolen. There is about a $10M difference between EE's contract and Rolen's contract for this year and 2010. Trading one of those three saves the Reds between $15M and $18M depending on who it is.6:08pm: AOL FanHouse's Ed Price tweets that it's possible for the Reds to acquire Rolen, "but a lot would have to happen," according to a source.
