The thing is, Donaldson is going to be 34 next year. It seems like most teams have smartened up from giving a player that old a longer multi year deal while also giving up a pick. So offering him a QO might very well sap his value and force him to accept.
Conspiracy theory, but there is always a chance we gave him a gentleman's agreement that we wouldn't offer a QO in order to get him to sign with us.
That would absolutely be the best case scenario.
My ideal off season would be JD accepts the QO, Grandal takes a 2 year deal, and a good RHH OFer is signed to platoon with Ender and Markakis.
