Never is such a big word; it comes close to being a word 'never' to be used when discussing the future. Discarding that wisdom, I predict that for Alabama Football, two things will never happen again. Expanding such boldness, I predict the same two things will never be repeated by any college football program.
Not only Alabama Football's two greatest head coaches, but college football's two greatest head coaches made achievements that will never be replicated.
For Nick Saban, there are multiple levels of greatness. It is unlikely that Nick Saban's five National Championships in just nine seasons will ever be equaled.
