New England's legacy of success, which McDaniels has been part of, might have played a role in convincing him to stay. He has won five Super Bowls in New England since joining Bill Belichick's staff in 2001. His tutelage of Tom Brady -- arguably the greatest quarterback in NFL history -- has made him a popular name among head-coaching searches for years, despite his disappointing stint with the Broncos. With defensive coordinator Matt Patricia taking over the Detroit Lions' coaching job, McDaniels will help Belichick maintain some continuity at the highest levels of his staff.
