As I noted last fall, this is exactly what Caleb did constantly his last season at USC. It continues to be a huge problem and speaks to the possibility that--despite his athletic talents--Williams has difficulty processing what he's seeing on the field. This has sometimes been referred to as "seeing ghosts" and it is not always a correctable problem. FWIW, In one of the TSW mock drafts in April, I got destroyed for taking Jayden Daniels for the Bears over Williams with the first overall pick.
It's too early to write Williams off completely, but there are a ton of red flags here and we could be looking at another Bryce Young-type situation, especially given the talent Williams was given to work with...
