If I remember correctly that was a Peyton Manning .v. Ryan Leaf debate as to who would go #1. I know the Colts have said, it was always going to be Manning but the public did not know that at the time. Hindsight says the Colts made the right decision.
I don't think comparing Caleb Williams to Peyton Manning is fair to Caleb. Peyton was as polished of a QB as there ever was entering draft, Caleb needs some polishing up and I don't trust the Bears to do that properly.
If the Bears end up drafting Williams, I'll root for him to succeed but I think I rather follow the 49ers playbook and build up the roster and find a plug and play guy.
