Context: History.
Even after the emergence of the professional National Football League (NFL), college football remained extremely popular throughout the U.S. 
Although the college game has a much larger margin for talent than its pro counterpart, the sheer number of fans following major colleges provides a financial equalizer for the game, with Division I programs  the highest level  playing in huge stadiums, six of which have seating capacity exceeding 100,000. In many cases, college stadiums employ bench-style seating, as opposed to individual seats with backs and arm rests. This allows them to seat more fans in a given amount of space than the typical professional stadium, which tends to have more features and comforts for fans. (Only two stadiums owned by U.S. colleges or universities  Papa John's Cardinal Stadium at the University of Louisville and FAU Stadium at Florida Atlantic University  consist entirely of chairback seating.), The Sun Belt Conference is a collegiate athletic conference that has been affiliated with the NCAA's Division I since 1976.

In team sports, matches of this type are often used to help coaches and managers select and condition players for the competitive matches of a league season or tournament. If the players usually play in different teams in other leagues, exhibition games offer an opportunity for the players to learn to work with each other. The games can be held between separate teams or between parts of the same team., A defensive coordinator is a member of the coaching staff of a gridiron football team who is in charge of the defense. Generally, along with the offensive coordinator, he represents the second level of command structure after the head coach. The defensive coordinator is generally in charge of managing all defensive players and assistant coaches, of developing a general defensive game plan, and of calling the plays for the defense during the game. At higher levels of football (college and professional), the defensive coordinator typically has a number of assistant coaches working under him who are responsible for the various defensive positions on the team (such as defensive line, linebackers, or defensive backs)., A county seat is an administrative center, seat of government, or capital city of a county or civil parish.
