Edge has 3 title matches and Miz just one. Fair Much?

Why are they going out of their way to protect Miz. Don't get me wrong I am thrilled for Jerry but Edge is putting his body through heck in the EC and fighting in these dumb rematches from hell by Vickie. Did WWE Creative figure out that there was no way to make Miz credibly win in the Chamber so they had this cop out match with Lawler where even there he won't go over cleanly. The build up to Mania so far has been the weakest in a decade by my books
