I'm not an "insider" so perhaps that is where people have heard rumblings of this as a possibility? But even then the rumors tend to trickle down to the common folk, and I don't recall hearing or reading anything about this prior to the actual announcement.
Unless there have been rumors that I just haven't heard, saying that this was inevitable just seems like a convenient way of brushing off the sting of losing a top recruit IMO.
Hopefully this is another d. Dawson situation and he comes back to the good guys in the end.
