These comparisons of Diaz to coaches or schools of different era's is a fools argument usually started by small minded posters.
It's like arguing who was/Is better Michael Jordan or LeBron James.
The fact is Diaz has been at Miami, the defense should not be struggling like it is. And the reality is he has surrounded himself with coordinators who aren't very good.
If he makes no changes to the staph this off season, he will he fired. And it makes no difference what happened to Jimmy, or Butch, or Golden, or Don Shula, or Jon Gruden, or, or ,or. This is now, deal with it.
