Saw a play Friday night I’ll try to describe. A is in a no huddle hurry up offense with the LOS about A’s 40. R maintained his rhythm in giving the ready. Just before R gave the ready, B sends 2 subs onto the field. The first substitution was made with no problem. The second had to go to the far side of the field, notified his player (B76) who began leaving the field immediately but with no sense of urgency. The ball is snapped with B76 near the inbound marks nearest his team box on A’s 45. A throws a completed pass near the 50 on B’s sideline with B76 still ambling along at A’s 45 about the top of the numbers now. B76, seeing the pass completion, actually pauses for a half a second, then changes direction and begins running toward the receiver. B27 makes the tackle at the 50 and B76 pulls up, then continues to the team box. B76 did not hit anyone or hinder anyone’s path to the ball but was in a position to make the tackle had B27 not.

IS (dead or live) or IP? What would you call?
