McDaniels, 43, has been the Patriots offensive coordinator since he rejoined the team in 2012. The unit picked up right where it left off under McDaniels' watch, ranking in the league's top 10 on eight separate occasions from 2006-2008 and 2012-present. The Patriots boasted the league's No. 1 offense in 2007, 2012 and 2017. McDaniels has worked closest with future Hall of Famer Tom Brady, who has made the Pro Bowl 10 times with McDaniels as his quarterbacks coach and/or coordinator. New England won three Super Bowls during McDaniels' current stint (2012, 2015, 2017) and three others (2002, 2004, 2005) when he was establishing himself as an assistant during the early part of his career.

McDaniels has head coaching experience, too. From 2009-10, McDaniels served as the head coach of the Denver Broncos, going 11-17 before his dismissal. McDaniels won his first six games as a head coach but the team ultimately hit a rough patch and finished 8-8. The Broncos were 3-9 before parting ways with him in 2010.

McDaniels began his coaching career as a graduate assistant under Nick Saban at Michigan State in 1999. He joined the Patriots in 2001 as a personnel assistant and steadily rose the ranks before taking over as quarterbacks coach in 2004. He assumed the offensive coordinator role in 2006 and held that position until he left for the Broncos.
