Davis was enamored with McDaniels' offensive system and his pedigree as a longtime offensive coordinator for the New England Patriots, with whom he won six Super Bowl rings.
But the offensive success did not translate to Las Vegas, and the Raiders suffered some of the most embarrassing defeats in franchise history under the McDaniels-Ziegler duo. That included blowing a 20-0 halftime lead against Arizona for the biggest collapse in franchise history, losing to Indianapolis in the Colts' first game with Jeff Saturday as interim coach after he had never coached above the high school level, blowing a double-digit lead to Baker Mayfield and the Los Angeles Rams two days after Mayfield joined his new team, and getting shut out in New Orleans when the starting offense failed to cross the 50-yard line.
