I just imagine that Mueller and Cam have a plan or an idea of what they want to do. It may not be what we wanted or expected, but they probably know how they want to handle it. They may still have plans to get Green but don't want to surrender what Peterson wants and are waiting him out. If Green knows their plans and really wants to come to Miami he is probably playing the waiting game to see what KC does.
If I remember right didn't Mueller make a statement early on that he would bring in quarterbacks rather than a quarterback?
