After being drafted, there was a lot of hype around Robert Williams. He was seen as a steal of the draft, with the kind of physical talent that could have made him a lottery pick. There were, however, reasons that he dropped, and we have already seen some of why.
There have been multiple occasions now where Williams has overslept, missing the opening press conference and a flight that took him out of a summer league practice. That alone made some people sour on him, but lower those expectations could probably be good for him.
In the end, all the outside noise really does not matter, and it is about how the Boston Celtics feel about him.
