How many ways to get first down?

Answer 1

Alot, either pass the ball, which is the best choice or run the ball. If in a long yardage situation, the best choice is to pass the ball. Another one, but also dangerous, fake punt on 4th down and run or pass it with the punter. The same on field goals.

Answer 2

It depends on where the ball is placed when the offensive team has it. But there can be numerous amounts of first downs.

Answer 3

You start out with a 1st and 10 yards and you have 4 plays to get another first down.
