Coach Rehiring

Generally, the approach that I take in determining whether to rehire, or do a rehire and promotion of a particular coach who is willing to be rehired, is to look at how he ranks in his primary rating for his role with other coaches in the world for that particular level and role from the previous season.  You can look at last year's coaches across the world via the "Coaches" report.  If his primary rating ranks within the top half (or ideally, top ten) of last season's coaches for the level/role you are considering him for, then he is a good candidate for rehiring and possibly promoting.
