Miami Dolphins coach Nick Saban is offering his support to troubled running back Ricky Williams. In his first comments about Williams' latest failed drug test, Saban said Friday he wanted to help Williams stay clean, avoid any additional trouble and help the NFL keep drug tests confidential as required by league rules. "We want to support every player, and I think every player knows he has a responsibility for what to do and what not to do," Saban said. "As a coach, I also feel a responsibility to put a player in the best situation possible so he can have success."
