This has a little different twist than the others.

So how about the situation where there are 4.5 secs on the clock, A trailing by 2, B1 shooting 2nd of 2 free throws. Misses, ball controlled by A1 in corner(first touching), dribbles twice passes to half court(center circle) to A2. A2 dribbles then passes to A3 on wing opposite table. A3 shoots airball, within 2ft or so of rim, that is tipped in by A4 just before the horn goes.

Pretty sure that this situation would have taken longer than 4.5 seconds. New Trail and New Lead both saw that clock hadn't started at different points. Trail after first dribble by A1. Lead as ball was passed to A2 at center circle.

How would this be handled? Obviously New Trail and New Lead should have shut the play down as soon as they saw the clock hadn't started but they didn't and this has occurred. No one had definte knowledge of how much time it actually took.
