Well, I can assuredly give you a list of reasons why Saban's teaching is overblown, and, despite the credit he gets for still to this day being involved in the secondary coaching at the Saban Plantation of Tuscaloosa, his specialty has become more about leaning on the coaching of others and having an open checkbook.
I mean, I could, but you wouldn't know WTH I'm talking about, so I won't.
Fact of the matter is, Saban was incredibly fortunate to land at Alabama when he did. The school's resources and coming along right at the time when big $ opened a Pandora's box in college football made his legacy. Not saying Saban is a dummy, but look to his time with the Dolphins to balance out those Bama accolades...
