The Las Vegas Raiders interviewed Kubiak before the Super Bowl but could not appoint the Seattle Seahawks offensive co-ordinator until after the title decider.
The 38-year-old, whose father is Super Bowl-winning coach Gary Kubiak, became the 25th head coach in Raiders history less than 48 hours after helping Seattle become the latest NFL champions.
Kubiak was flanked by some Raiders legends, who were involved in their three Super Bowl wins between 1977 and 1984, but the franchise has struggled in recent years and has the first pick in this year’s draft.
“It’s not daunting at all – it’s a blessing,” said Kubiak, who replaces veteran coach Pete Carroll. “I look at it as ‘You know what? What a great challenge.'”
LaFleur joined the Arizona Cardinals on a five-year contract to succeed Jonathan Gannon.
The 38-year-old is the younger brother of Green Bay Packers head coach Matt LaFleur and has spent the past three seasons as the Los Angeles Rams’ offensive co-ordinator.
“I couldn’t be more fired up,” said LaFleur. “Having competed against them in the NFC so many times in recent years, I know the type of talent and toughness the team has.”
