McDaniels spent the last eight seasons (2001-08) on the coaching staff of the New England Patriots, helping the franchise win three Super Bowls, four AFC championships and six division titles en route to posting the NFL's best overall record (111-34 / .766) during that time. He was the Patriots' offensive coordinator/quarterbacks coach during the previous three years (2006-08), directing an offense that led the NFL in points per game (28.8) while ranking second in the league in yards per game (370.8) and third in fewest turnovers (63) over that stretch.
McDaniels worked as New England's quarterbacks coach from 2004-05 after serving as a coaching assistant for the club from 2002-03 and as a personnel assistant/coaching assistant in 2001. His coaching career began in 1999 as a graduate assistant at Michigan State University.
Despite a season-ending injury to starting quarterback Tom Brady in Week 1, New England's 2008 offense finished the year with an NFL-best 356 first downs and ranked fifth in the league in yards per game (365.4) under McDaniels. His coaching helped backup quarterback Matt Cassel, who became a starter for the first time since high school, total the eighth-most passing yards (3,693) in the league.
In 2007, McDaniels coached on a Patriots team that was the first in NFL history to post a 16-0 regular-season record and advanced to Super Bowl XLII. McDaniels' offense was one of the most productive in NFL history with the Patriots setting league records for points scored (589 / 36.8 ppg.) and touchdowns (75). Individually, Brady set an NFL single-season record for touchdown passes (50) to earn MVP honors while wide receiver Randy Moss caught the most touchdowns (23) for a season in league annals.
The Patriots won Super Bowls with McDaniels on their staff during the 2001 (XXXVI), '03 (XXXVIII) and '04 (XXXIX) seasons.
McDaniels played quarterback and wide receiver at John Carroll University (University Heights, Ohio) from 1995-98 after finishing his prep career at Canton McKinley High School (Canton, Ohio).
Born on April 22, 1976, in Barberton, Ohio, McDaniels and his wife, Laura, have one son, Jack Thomas, and one daughter, Maddie.
