William LaQuayne Yates is an American football coach and former offensive guard who is the assistant offensive line coach for the New England Patriots of the National Football League (NFL). He played college football at Texas A&M and was signed by the Miami Dolphins as an undrafted free agent in 2003.

The 2005 season was the New England Patriots' 36th in the National Football League (NFL), their 46th overall and their sixth under head coach Bill Belichick. With a Week 6 loss to the Denver Broncos, the Patriots failed to either improve or match their 14–2 record from last season; they finished with a 10–6 record and the division title before losing in the playoffs to the Broncos, ending their hopes of becoming the first NFL team to three peat in the Super Bowl.
