Mackenzy Bernadeau (born January 3, 1986) is an American football guard for the Dallas Cowboys of the National Football League. He was drafted with the 250th pick by the Carolina Panthers in the seventh round of the 2008 NFL Draft. He played college football at Bentley University.
Bernadeau attended Waltham High School, before moving on to Bentley University in his hometown of Waltham, Massachusetts, where he majored in management. He started 37 straight games (25 at left tackle and 12 at left guard), before suffering a knee injury in the sixth game of his senior season. He is the second Bentley player to ever be drafted and the only one to make an NFL roster.
Bernadeau was selected in the seventh round (250th overall) of the 2008 NFL Draft. He was the first Northeast-10 Conference player ever drafted in the NFL. He became a starter in 2009 and his best season with the Panthers came the next year, when he started 12 games. In 2011, he lost his starting position to Travelle Wharton.
On March 14, 2012, Bernadeau signed with the Dallas Cowboys as a free agent. After having hip and knee surgery in the offseason, his level of play suffered, even though he started 16 games for the first time in his career.
The next year he had another offseason surgery, this time in his right shoulder. After starting the first 3 games of the 2013 season, the Cowboys signed former Pro Bowler Brian Waters to start in place of Bernadeau and improve the level of play on the offensive line. After Waters was lost for the season with a triceps injury, Bernadeau regained his starter role and went on to play his best football as a Cowboy.
Looking to improve the guard position, the team selected Zack Martin (named All-Pro as a rookie) in the first round of the 2014 NFL Draft and moved Bernadeu to compete for the left guard position, which eventually went to Ronald Leary. He only started one game in place of an injured Leary and remained as a backup for the rest of the season.
Bernadeau is of Haitian descent. He is one of five siblings. Bernadeau enjoys karaoke as he is a world recognized champion in the activity. Competing in Berlin in 2012 and Montreal in 2013 Bernadeau took home gold in both events. He credits his mother for giving him his sweet sounding voice.
