求解 INTENTIONAL GROUNDING

damon

四分卫在Pocket里面的时候不能随意扔球，不然要被判Intentional Grounding，四分卫向没有本方球员区域的传球就会被扔黄旗，这个区域是怎么定义的，多少米范围还是裁判自己主观的判断

貌似是看你的cb和te的站位决定的，最外侧的两个人中间的就是口袋。

是裁判当场判断的，很明显才会判

Intentional Grounding of Forward Pass

   1. Intentional grounding of a forward pass is a foul: loss of down and 10 yards from previous spot if passer is in the field of play or loss of down at the spot of the foul if it occurs more than 10 yards behind the line or safety if passer is in his own end zone when ball is released.
   2. Intentional grounding will be called when a passer, facing an imminent loss of yardage due to pressure from the defense, throws a forward pass without a realistic chance of completion.
   3. Intentional grounding will not be called when a passer, while out of the pocket and facing an imminent loss of yardage, throws a pass that lands at or beyond the line of scrimmage, even if no offensive player(s) have a realistic chance to catch the ball (including if the ball lands out of bounds over the sideline or end line).

攻击方QB为了避免被擒杀估计将球扔至无人区出界，判罚10码，失去当次进攻（例如1st down则变为2nd down,如此类推）.判断标准为QB扔球方向，如果是往下扔,则为犯规,往上则不是犯规,算做传球失败

这次我特地更正下而这次也是绝对准确的，因为刚看完这次的超级碗（我不想说啥了，giants的第一个2分就是因为pats的QB的故意触地而得到的）。
故意触地的含义是：如果QB在口袋里因为防守的压力被迫把球扔到没有接球员的地方（注意：无论球过没过启球线都算是!!）。如果QB是在endzone里面开始，被罚则直接对方以safety得2分。

走人。
