Actually, it was the organization. Coaching was not good for them but look at the squad that the Bears fielded since Fields got there and look at what they did for Williams. Many pundits feels like this is the best situation a #1 QB has ever been drafted to and they are not lying. And more often than not, coaching/scheming/team are major factors in success. I'm not saying that Fields is better than Williams. I'm just saying that Williams is starting with an infinitely better situation than Fields has ever had in the NFL. That's all.
I'm not critical of success. He was key in their first 2 super bowls (*cough*and refs against 49ers*cough*) but the last Super Bowl was all defense and if it wasn't for them, this would have been another loss. But again, we saw the Chiefs not score a single point in the second half of the AFCCG and still won. I knew 49ers had their work cut out for them.
