Though he never officially coached under Bill Belichick, Kliff Kingsbury still learned a lot about his eventual career during his time in New England.
Kingsbury, the new head coach of the Cardinals, was a quarterback when the Patriots made him a sixth-round pick in the 2003 draft. After an injury meant he was ruled out for the season, Kingsbury effectively became a coach, working under then-offensive coordinator Charlie Weis to help prepare the team.
It was in this period that Kingsbury got his first glimpse at the coaching world. His admiration for Belichick grew during the experience.
