End of game situation

[jritchie]

0.7 left, tie game. Under A basket, A ball, I am at lead, ball is lobbed up to big man at the rim, bounces off hands and hits rim and directly down into A2 hands who catches and shoots layup for win before the buzzer! Thought it was a long 0.7 myself,(of course home team had ball) but with me being lead and not having clock, I didn't say anything as the trail and C ran off the floor avoiding overtime! Is it my place to call a conference before leaving the floor to make sure the clock started properly or should I just leave the floor because they had the clock? Just wondering.
