"Washington Redskins coach Mike Shanahan issued a public challenge Monday to left tackle Trent Williams, saying the 2010 first-round draft pick needs to continue his on-field development and demonstrate improved commitment and maturity following his drug-related suspension. The coach also said he sees a change in tight end and /free-agent-to-be Fred Davis, who also ended the season on a four-game suspension for failing multiple drug tests.

Williams was the first draft pick of Shanahan's tenure as head coach of the Redskins. Washington selected him fourth overall out of Oklahoma, and Williams this season was picked as one of the team's offensive captains."
