The second annual NFL Players Association player survey was the first time head coaches and ownership groups were ranked and graded.

More than half of the league’s head coaches were given an A- or better, but three head coaches stood out as among the best bosses in the business.

Leading the way was three-time Super Bowl champion and Kansas City Chiefs head coach Andy Reid, who received a 9.77 out of 10 from his players. Minnesota Vikings head coach Kevin O’Connell was ranked second and was ranked first in the “willing to listen to the locker room” category. Dan Campbell, the Detroit Lions head coach, was third overall and the only other coach to receive an A+.

Nine coaches received “A” marks and another seven got A-.

On the flipside, former Washington Commanders coach Ron Rivera had the second-lowest grade (C), while fired Las Vegas Raiders head man Josh McDaniels received a D. Coaches were graded overall, how much they were willing to listen to players, and how efficient they were with players’ time.
