How could anyone be happy with, or even tolerate, a Bobo/Norvell hire? All they have done as a head coach so far is inherit a program built up by their predecessor and not completely wreck things yet. That's basically what Butch was. An unjustifiably stupid hire.
If you're going to look at coaches who inherited a relatively built team/program from their predecessor, there should be some indication that they've been able to maintain or exceed the standard set by the predecessor over a long period of time. (Patterson, Peterson).
Also, if you think Tennessee should pursue DJ Durkin, it looks like you've accepted that Tennessee should just start at the bottom tier and work your way down.
