Francis has been pope for 4 years.  He is trying to balance the imbalances created during the 35 years of JPII/B16.  It will take some time, so until there is some kind of balance, he must try to appoint as many progressives and pastoral types as possible. It is not likely he will have another 30 years to undo the damage that has been done by the heavy weighting to the "conservative" side that exists now and which has contributed to the loss of tens of millions of Catholics in the developed countries of the world (those where the vast majority of the population are educated)
