When I go to Staff I can't fire coaches, only edit them. I can't "click VIEW COACHES" to see coaches available for hire" either... Is that something we can change or is that a PF21 goal?

To be able to hire/fire instead of just edit coaches, so we can track stats etc?

coach hiring/firing is done in the coachsigning phase at the start of each season. I would guess you are in some other phase since the buttons are locked.
