Redskins coach Joe Gibbs upgraded his offense Thursday by adding one of the brightest offensive minds to his sidelines. Gibbs hired Chiefs offensive coordinator Al Saunders as assistant head coach and offensive coordinator, convincing him to sign a three-year contract worth more than $2 million a year. Saunders was considered the leading candidate for the Raiders head coaching job after their first set of three interviews but he had not been offered the job. With only two head coaching opportunities left -- Oakland and Buffalo -- Saunders was fielding a lot of phone calls by teams and coaches who wanted him as their offensive coordinator. The biggest surprise was the arrival of Gibbs in Kansas City on Wednesday. Gibbs made Saunders an offer he couldn't refuse, a deal that trumped a chance to be a head coach. After the season, Gibbs talked defensive coordinator Gregg Williams into staying instead of taking a head coaching job on an other team. Williams received a three-year, $7.8 million deal. His deal, the most lucrative ever for an assistant coach, includes a $1 million bonus if he is not named the Washington head coach when Gibbs retires.
