To think Muller (apparently) tried to play it safe, only to be shunted aside. That is food for thought.

He may have been doing that in the hopes of keeping his job longer so that Francis wouldn't replace him with someone who's heterodox sooner. So, it may have been with good intentions, but it's had bad results.

That makes sense. It appears that Muller would have traditionally occupied this post, Prefect of the Congregation for the Faith, for a few years longer. I can only imagine his shock and dismay at such a sudden dismissal.
