Why not Andre?

Why was Andre never given an actual run with the WWF title in the 70's or early 80's in the pre-Hogan era(not counting the 30-second reign on The Main Event)? He was super-over, the fans loved him and I'm sure he was a draw…was Backlund really a more worthy champion than Andre? Why was this never done? 

Andre never wanted it and he made far more money as his own touring attraction, rather than having to deal with the politics involved in being champion anywhere.  Plus, much like the Undertaker, you can do one tour with the champion on top and one tour with Andre on top.
