Time for underwood to learn a lesson

Look Im a bryce supporter to the end and getting rid of him is not a option. But its clear his mental attitude is not there though he's developing he just imploded today. Honestly I think the only way to get him to realize that hes not Mr. hotshot is to bench him for a game or 2. I don't want to hurt his confidence but I'm the same age as him and I can tell he's not realizing his mistakes. The talent and athleticism is there and he can develop into a really good qb but I think his ego is making it so its not coming across as his fault. Is it time to give up on him absolutely not. Can he be a good quarterback absolutly. But I think he needs to get the message that this is on him and the only way to do that is to temporarily bench him.
