Give Rizzo some time. He does a lot of stuff after the winter meeting.
But I tend to agree with you - we need a plan for closing - even if it's two very good relievers closing-by-committee - bullpen help, and a good bench bat. Maybe Stephen Drew.
It's really too late. The market is sky high on back of the pen guys. Rizzo either sells the whole farm system or just kicks the can to the post season where Dusty freaks it up again.
