Danno,

You might remember Tom Doyle  highlighting three bishops in the Catholic world, who had the courage to speak out and be critical of the church's handling of the abuse scandal. They were Diarmuid Martin (of Dublin) ; Robinson of Australia (to the best of my recall) and an American bishop. Tom indicated that both the Australian and American bishops had been "retired" (stood-down) and that Archbishop Diarmuid Martin was the only man left in place.

Diarmuid Martin had a diplomatic career and was the Vatican's rep at the U.N. when he was returned to Dublin, to replace Cardinal Desmond Connell ; who as an ultra conservative,  had mishandled the clerical abuse scandal.  The Judicial Review Report into the Dublin Diocese was extremely critical of him. He was the Cardinal who defined the "Mental Reservation" tool, to the Judicial Review.

Archbishop Diarmuid Martin would make an excellent replacement for Muller. He would however, be a great loss to Dubin. He is an honest broker.
