Nothing is technically asked of a head coach when he leaves for another job. Some meet with their team, others don't, some have a farewell tour of sorts, while others leave quietly. It all depends on the personality of the man who has made the decision.
Every once in a while, a coach will get in touch with the local paper / media to issue a final thank you, and that's exactly what Matt Rhule did following his decision to leave Temple for Baylor.
