I think Dallas40oz is right, C-Mike is going to be an ERFA type FA. But that's actually a good thing, since the minimum price for an ERFA player is right around league minimum salary, whereas a RFA tag is a decent chunk of change. The only drawback is that Seattle would have to make the decision to sign Michael as an ERFA before the ERFA / RFA deadline, which occurs a few weeks before UFA begins. It should be a no-brainer if Michael plays well, but you never know.
