Williams was most notable for being the first player on the Buffalo Bills squad to don number 31, which had been "retired" to represent the spirit of the franchise. Since Williams wore the number, the Bills have allowed anyone to wear the 31 jersey; it was later worn by Dwayne Wright, who like Williams, went to Fresno State. Jairus Byrd wore the number before becoming a free agent; he used it because his college number, 32, was unofficially retired because of O. J. Simpson.
After retiring from football, Williams became a football coach beginning in 1997 as a graduate assistant at Fresno State.[4]
