I'll take it one step further. I agree that he thinks his way will eventually work.
But beyond that, he doesn't actually care if his way will work. It will be his way regardless of if it works. He "wants" it to work but that's not the most important thing to him. Being in charge is the most important thing. Even if it doesn't work he never wants to not be in charge.
If you gave him a crystal ball and showed him with 100% certainty that he never will win a super bowl his way and the only way to change the future is if someone else was in charge, he still wouldn't change anything.
We are all hostages to that as fans and that makes it incredibly frustrating to continue to root for them.
