nfl rules can the ground cause an incomplete pass
Fumble This is not the same thing as when a forward pass is attempted and is not caught. In this latter case, it is simply an incomplete pass. However, if the receiver catches the ball, but then drops it after gaining control of the ball, that is considered a fumble.

National Football League Draft Players who have been out of high school for at least three years are eligible for the NFL draft. The rules do not state that a player must attend college, but virtually all of the players selected in the NFL draft have played college football, usually in the United States but occasionally from Canadian universities as well. A few players are occasionally selected from other football leagues like the Arena Football League (AFL), the Canadian Football League (CFL), and the German Football League (GFL). A small handful of players have also been drafted from colleges who played other sports than football.
American football Football games last for a total of 60 minutes in professional and college play and are divided into two-halves of 30 minutes and four-quarters of 15 minutes.[71][72] High school football games are 48 minutes in length with two-halves of 24 minutes and four-quarters of 12 minutes.[73] The two-halves are separated by a halftime period, and the first and third quarters are also followed by a short break.[71][72][74] Prior to the start of the game, the referee and team captains for each team meet at midfield for a coin toss. The visiting team is allowed to call 'heads' or 'tails'; the winner of the toss is allowed to decide between choosing whether to receive or kick off the ball or choosing which goal they want to defend, but they can also defer their choice until the second half. The losing team, unless the winning team decides to defer, is allowed to choose the option the winning team did not select, and receives the option to receive, kick, or select a goal to defend to begin the second half. Most teams choose to receive or defer, because choosing to kick the ball to start the game would allow the other team to choose which goal to defend.[75] Teams switch goals following the first and third quarters.[76] If a down is in progress when a quarter ends, play continues until the down is completed.[77][78][79]
