I don't like the idea of getting rid of kickoffs, but what I DO like is the idea of replacing onside kicks with an attempt of 4th and 15 from the 30 yard line. It would make potential comebacks much more exciting, onside kicks are so rarely successful that they are basically irrelevant. To me it's pretty disappointing when you see a team start to make an epic comeback and start heating up on offense but then the comeback falls short just because they are unable to recover an onside kick at the end.
why don't we just keep giving the losing team the ball until they comeback?
