Any time Peyton Manning is directing an offense, the unit is going to operate at a breakneck pace to take advantage of the wily veteran's ability to control the game at the line of scrimmage. Manning is one of the few quarterbacks in the NFL capable of calling his own plays; he is masterful at deciphering coverage at the line and checking to the ideal play to exploit the vulnerable area of the scheme. Manning manipulates tempo to keep the defense in personnel packages that favor the Broncos while eliminating defensive substitutions/rotations and wearing down the opponent's front seven. The warp-speed pace also threatens defensive communication, thus limiting the calls available to the opposing coordinator. With physical fatigue and spotty communication spawning defensive breakdowns at every level, the Broncos scored the most points in NFL history during the regular season.
