McDaniels will become the Broncos’ 12th head coach, succeeding Mike Shanahan, who was fired Dec. 30. Shanahan holds the Broncos record for most wins by a coach with 138.
McDaniels has spent his whole career with the Patriots, which started in 2001 as a personal assistant before rising to offensive coordinator.
Since McDaniels' arrival in 2001, the Patriots have experienced the success of quarterback Tom Brady and won three Super Bowls, and just fell short of a historic 19-0 record last season.
This season, even with Brady going out in the opener, McDaniels, was able to work with Matt Cassel and help the Patriots to an 11-5 record.
McDaniels will take over a Broncos team that has failed to reach the playoffs three straight seasons for the first time since 1980-82.
