不管是自己出界还是被推出去，都是illegal catch
NFL rule book:
It is a foul for illegal touching if a forward pass first touches or is
caught by an eligible receiver who has gone out of bounds (either by his own
volition or by being legally forced out) and has re-established himself
inbounds.
【在 T***u 的大作中提到】 : OBJ的2 point conversion被吹掉了 : 显然是被推出界而不是主动跑出界的
