No position in all of American sports is more important than quarterback.
The quarterback touches the ball on every single play. An elite QB can drag an otherwise average roster deep into the playoffs, but a bad signal caller could doom even an elite roster.
In my NFL Power Rankings, quarterback reigns supreme by a wide margin. Following the Football Outsiders model, I count QB at over 40% of the entire offensive unit ranking and more than 25% over the overall roster ranking.
Take Patrick Mahomes.
