Lots of rumors this week.
Part of this rumor is that the formal announcement of Brocker's extension also included the announcement of Fisher's extension. Still haven't seen the formal Brockers announcement, though it's been publicly stated he's extended.
Again, that's a rumor. Lots of tweets come out following the rumor.
Another rumor this week was that Fisher didn't want Goff (similar to what happened in Tennessee). However, that has also been shown to be false and Fisher did want Goff.
No rumors on him being fired yet. But, I highly doubt these extension rumors are true as of right now. Maybe before Monday night it was the plan.
Extending Fisher right now is just not believable. Although, at this point I guess nothing would completely surprise me.
