Not sure about that. If Matt Davidson hits 20-25 HR's this year for CHI then this was not a good trade unless Reed has a good year. Remember, Davidson is only 22 so he is actually younger and under club control longer than Reed.
He better hit more than that for the Sox considering he is a DH. The guy is worse in the field than Trumbo, but at least we can hide Trumbo in LF instead of having Davidson as a liability at 3B.
