Finally got around to watching it. I've read it since Saturday but I wanted to observe Billy so I could get a better read on the man himself.
1. He's medicated. His words are slurred. I watched about 10 different videos of him talking and he never sounded so out of it. That would explain his lethargy from last year when he at least had an outburst on the sidelines.
2. He's getting adversarial.
@soflagator alluded to this in many posts. He's in over his head and can't admit he was wrong, this ties in with the other points and I'll elaborate below.
3. He's in way over his head.
4. He's not very bright
Let me give my evidence for points 2,3,4. He's not very bright because he thinks he walked away with Sabans secret sauce. It's like that old fable about 3 blind men touching an elephant. One touches the leg and says it's a tree, one touches the tail and says it's a rope, one touches the ear, etc. Muschamp worked with saban, and said it's all about defense and run game. Billy worked with Saban and says it's all about details and processes, Smart worked with saban and was like, it's an elephant dummies!
He's in over his head because he is a great recruiter and in the middle of the pack you can put beat 60 by being 50. It's like any TV show or movie where the coach finds the tall guy for basketball or puts a boy on a girl's team (ladybugs, little giants, etc)
Now that his flawed take away from Saban isn't working because he doesn't have the secret sauce he's angry with anyone who points out his shortcoming. Thus the insistence on sticking with his system.
Lastly, to his intelligence, as many have said it's a bad recipe. He really believes that somehow having a system (that literally every coach or every company has) is all the difference. Think about how stupid this is, it's like a company saying, I know our stock is tanking and the company is going bankrupt but we've instituted a new system where all our employees have to clock in on time and if we stick to the plan we'll be profitable again. The result is everyone clocks in on time but they forget to submit invoices, they leave the lights on at night and forget to lock the doors while inventory gets stolen.
Next time we hire a coach we need a smart, innovative, adaptable person who will do anything to win
TL/DR Billy is a moron
