How did I know you were gonna say Tulo before even clicking on the thread?
Jesus, so many people here don't understand how good Tulo can be with the bat. This js like the Edwin situation all over again. Trade the slumping bat right?
Anyways, IMO Tulo/Donaldson/Martin are the least likely to be traded, only for the fact that they all provide defensive value in addition to their bats.
