Paul said that Deron didn't want to be the MVP that he thought he was before he got there.
Pierce wasn't exactly good himself with the Nets. He also called out Joe Johnson on that team and Robin Lopez went from a budding start to a backup on a bad team.
While I do believe Deron shares plenty of the blame, so does everyone else there. Williams clearly isn't the guy who was 1-2 with Chris Paul in terms of NBA point guards. I just think he will help the Mavs.
