I think the issue with the Brown boys is maturity and not skills. They seem to be late bloomers. You might want to give them a couple of more years to mature mentally and physically.Fear of failure becomes all consuming and a paralyzing factor, manifesting as indecision, and skill errors on game day.
Which is exactly what we see with CB.
I could almost bet his decision making and skills are fine at training and more consistent with his 2019 highlights.
