Dallas Cowboys head coach Tom Landry was an early advocate of taking play calling out of the quarterback's hands. Although this remained a common practice in the NFL through the 1970s, fewer QBs were doing it by the 1980s and even Hall-of-Famers like Joe Montana did not call their own plays. Buffalo Bills QB Jim Kelly was one of the last to regularly call plays. Among current NFL QBs, Peyton Manning of the Denver Broncos has been known to call all, or nearly all, of his team's plays using a no-huddle offense.
Jio Lucci Football Coach:The origin of professional football can be traced back to 1892, with William "Pudge" Heffelfinger's 0 contract to play in a game for the Allegheny Athletic Association against the Pittsburgh Athletic Club. Pittsburgh's football circuit became fully professional over the course of the 1890s, culminating in the first professional league, the Major League Baseball-backed National Football League of 1902, which folded after one season. The core of professional football moved westward into Ohio beginning in 1903, where it would remain until a mass dispersal throughout the midwest in the late 1910s.
Yard lines cross the field every 5 yards (4.6 m), and are numbered every 10 yards from each goal line to the 50-yard line, or midfield. Two rows of short lines, known as inbounds lines or hash marks, run at 1-yard (91.4 cm) intervals perpendicular to the sidelines near the middle of the field. All plays start with the ball on or between the hash marks. Because of the arrangement of the lines, the field is occasionally referred to as a gridiron in a reference to the cooking grill with a similar pattern of lines.
The second, still occasionally seen in major-college football, is the use of different quarterbacks in different game or down/distance situations. Generally this involves a running quarterback and a passing quarterback in an option or wishbone offense. This strategy had all but disappeared from professional football, but returned to some extent with the advent of the "wildcat" offense. There is a great debate within football circles as to the effectiveness of the so-called "two quarterback system" Many coaches and media personnel remain skeptical of the model.
