It hasn’t been a head coach since 2010 when he was dismissed by the Denver Broncos early in the season. His overall record in that stint was just 11-17 and he didn’t last two full seasons.
McDaniels’ ability to catch on with the New England Patriots again as offensive coordinator since 2012 often enables people to look past his poor showing in Denver. His reunion with Bill Belichick has been successful, leading to four more top-10 offenses over five seasons (to go with two more in his three-year stint in New England before).
For the Jacksonville Jaguars, this is critically important.
