now see a year later - yes - it is irrational to assume the back-up is better. Funny, that you said MAYBE Mangum wasn't ready. Mangum still isn't ready. No more excuses like rain vs Wyoming. He just was not ready. He is not leaving a year early for the NFL. He will need to improve substantially to ever sniff the NFL. Irrational fans with irrational expectations were wrong - again.
Just like they were about the reality of who the new coaches hired would be given all of the constraints.
