It is a no brainer to say Evans and Wall could co-exist with "SOME SUCCESS".
The question is to what extent, how long, and if the result would be better than having the tandem of Evans and Cousins or Evans and Turner.
Also, these coaches would say things in the open just to be POLITICALLY CORRECT. It is much easier to do and it spares you from criticisms. Oh, and I am sure he is not biased at all too.
