A BALL is considered SCORED in an ALLIANCE’S GOAL if
A) a ROBOT causes one (1) of their ALLIANCE’S BALLS to cross completely and remain completely through the opening(s) of one (1) of their ALLIANCE’S GOALS without intervening TEAM member contact,
B) the ALLIANCE ROBOT last in contact with the BALL was entirely between the TRUSS and their ALLIANCE’S HIGH GOALS, and
C) the BALL is not in contact with any ROBOT from that ALLIANCE.
In this case, the robot that trussed the ball would not have met condition B.
Hope this helps.
EDIT: Wow, two people got in before me. This also happened to 135, who was against us, during Semifinal 2-1 at Crossroads, but it was mistakenly counted as scored by the referees. Our alliance knew it was a mistake, but we didn't question it because we won the match anyway.
