Miami Dolphins coach Nick Saban continued his long-standing support of running back Ricky Williams by testifying on Williams' behalf during an appeal of Williams' latest positive drug test under the NFL's substance-abuse policy. According to a source, Saban spoke for about 30 minutes Monday over the telephone. Saban has consistently said that he will support Williams through this process, that he doesn't believe Williams used drugs in this instance, and that Williams is one of the hardest-working players he ever has coached.
