Williams attended Queen Elizabeth High School (Halifax, Nova Scotia), where he played competitive football, soccer and basketball.
[1] He made an immediate impact in his first season with the Mustangs, setting a team receiving record for most yards per catch with 21.9, and was named an Ontario Universities Athletic Association (OUAA) second-team all-star.
Williams caught five passes for 157 yards and a touchdown to earn the Ted Morris Memorial Trophy as the game's most outstanding player as Western beat the Saskatchewan Huskies 35–10 to win the Canadian Interuniversity Athletic Union football championship.
[2] Williams earned All-Canadian honours in 1990 and again 1991, and graduated Western with a degree in economics, and school records for most receptions and most yards receiving.
Williams' accomplishments in Canada caught the attention of American scouts, and after his final season at Western ended, he received an invitation to play in the Senior Bowl in Birmingham, Alabama.
In 1993, the on-field high point of Williams' time with Dallas came on August 8, when he hooked up with quarterback Jason Garrett for 5 catches and 157 yards, including a game-tying 53-yard touchdown pass in the Cowboys' 13–13 tie with the Detroit Lions in a preseason game at Wembley Stadium in London, England.
The Cowboys earned a berth in Super Bowl XXVIII, but Williams was relegated to the inactive list when the team decided to dress an extra running back.
He did not play in the game, but earned a second Super Bowl ring as the Cowboys defeated the Bills 30–13 to win their second consecutive NFL championship.
The team nearly won the CFL's championship in his first year in the league, catching one pass for 13 yards in Calgary's 37–20 loss to the Baltimore Stallions in the 83rd Grey Cup.
