This is what happens to celebs and tyrants that surround themselves with 'yes, men.' In Saban's case, he's got an entire state that believes this with all their hearts (they also think they were jobbed out of TSIO by the refs) and can't understand that 2 losses doesn't entitle them to the playoffs. When people reinforce your sense of entitlement that strongly and universally you will eventually start to believe it yourself. Saban's been surrounded by this for more than a decade. To everyone else, his statement is absurd but to Saban it's logical (it's what his fans have been telling him on a loop).
If I ever find myself in a similar position, I'm keeping some of you curmudgeons around to remind me that every single thought I have isn't a good one just because I had it. lol.
