第一次修改wikipedia,主题竟然是橄榄球

Kuntakimp

改了http://en.wikipedia.org/wiki/Penalty_(American_football)
这个主题的,illegal contact,增加了the illegal contact is called only if the quarter back is still in pocket and the ball is still in his hands这一句,原文没有提及,是个疏漏,想想为大家作贡献,也挺爽的,再接再励,吃规则本来就是我们学数学的人的本性.

原来illegal contact还有这一个限制啊。好。

Kuntakimp

Delay of game (5 yards) - a defensive player delays the game or hinders the offense in hurrying to make the next snap. This happens most often in the last two minutes of a half when the offense is trying to go down the field in a hurry. The defense can also be flagged for a delay of game if a player spikes the ball after the end of a play. Referee signal: same as offensive delay of game.
