The Twins need to approach the Ricky Nolasco situation (or anyone else) as if it is a sunk cost regardless if it fits his dictionary definition. The Twins (or anyone on this board) should never say that he is too expensive to use as a RP'er because his contract pays him like a MOR starter. They are approaching the point where they have very little chance of recovering that value in any way. The Nolasco evaluation should essentially be based on 'he costs $0' for this particular role or we could call up X from the minors and pay them 500K and not continue to invest additional resources (roster spots, rotation spots, staff resources) in him. The fixed cost is basically sunk. It could be said that any long term contract is a sunk cost but most players have some chance of being productive enough going forward to return some value even if it isn't their full value.
