I have heard yesterday on some Catholic TV channel that Benedict had already done the theological clarification work during his mandate, and that Francis - who was already the runner-up to Benedict and knew he was likely to be next in line - knew his task would be more about preaching - thus his strong media game (and as he person it suited him well too, he seemed really approchable and outgoing).

Academic thought != clear, deep thought. Working out all the details is good, but getting to the crux of the matter is also needed.
