Monte Kiffen seems to want to come back to the NFL. He is 72. Old but definitely a great coach.
Controversy has surrounded Kiffin's departure from Tampa Bay. After Lane Kiffin signed with Tennessee, Tampa's typically stout defense underperformed. The Bucs lost their final four games of the 2008 season, ending up 9–7, and missed the playoffs. Before this, no NFL team had ever missed the playoffs after achieving a record of 9–3. Reports stated that Gruden refused to allow Kiffin to announce his departure to Tennessee mid-season. Allegations were made that Kiffin refused to participate in normal coaching meetings. Neither Kiffin nor Jon Gruden have openly discussed these events.(Wikipedia..Monte Kiffen)
