There is no valid argument for Saban as best coach of all time.
Put Tom Osborne at the head of that Alabama unscrupulous recruiting, and under the table funding scheme, with all that local talent, and I don't think he would have lost a single game in 6 or 7 years. Put Nick Saban at NU in 1991. would he have turned it around to go 60-3? OH! That's right! He would have lied to all of us and then bailed like he did to the Miami fans:

OR OH! Thats right! He never would have come here in the first place! Too tough of a challenge just like MIA was!
My Point: You can't say that he is the best coach ever when his major successes have come at Alabama, a school absolutely drowning in local talent , and ruthless boosters.
Tom Osborne Won 3 National titles as head coach at Nebraska, had his team in at least three more, AND called the plays for two other championship teams.
AT NEBRASKA, which is like barren of local schollies.
All Saban does is throw tantrums at everybody, and find other people to call the plays. TO would RULE Saban if they were forced to call their own plays.
