Don’t disagree if you measure by championships only.
But would Saban win at all levels like Cig? Would he have turned around IUP, Elon, and JMU? Would he have immediately made JMU successful their first year in FBS? Would Saban had won 11 games in his first year at IU and taken them to the CFP? Would he have won the Big 10 title, Rose Bowl and Natty in his second year at IU?
Saban was solid at Michigan State, but nothing like what Cig did at IU. Saban won with incredibly talented rosters with traditional power house teams at LSU and Bama.
Their journeys have been very different.
