This is fair, but the Cards are also firmly in a winning window and have a massive hole at catcher (while also still having Carlson, O'Neill, Donovan and Yepez who play OF). You could certainly see them trading from a position of strength to fill that hole - especially if they think Nootbar is a flash in the pan - or if they think they could just extend Jansen before he breaks out.
It will be interesting to see if the Cards get in on the Contreras sweepstakes, or go with a cheep defensive catcher like Maldonado.
