What do you think about the call on the red light situation last night? The referee's took over 10 minutes to view the monitor to see if the shot actually was made in time. The problem was that the clock said 00.0 but the red light had not gone on yet. They ruled that since the red light had not gone on yet that the shot was good and texas won.

What would you have done? Also who's fault is it?

Makes sense to me.
Speed of electricity (186,000 mps?) is quicker than a blink of the eye.
I guess Texas is not just good, but lucky, too.

You go by the horn, then the light, THEN the clock (because some clocks can really be at 0.01 - 0.09 seconds and show 0.0)

On some clocks, stopping the clock (for a whistle) when the horn is on can shut the horn off (dumb - but it's what some of us have to deal with). In that case, it's easier to see a light on a replay rather than hear a very short horn (especially true if the replay has no sound).

Mark Dexter Wed Jan 07, 2004 11:08am

BTW, since, by rule, the game has not ended, the team scored upon gets the ball for an inbounds with 0.0 on the clock. Good luck with the tip in that situation.

eyezen Wed Jan 07, 2004 01:15pm

I didn't see the play, but I would assume that since the discussion was whether the ball was released from the hand between the time the clock showed 0:00.0 and the red light came on that the red light indeed would of came on by the time the ball entered the basket, therefore the game would be over as there is no time left, wouldn't it?

The shot lives if released in time.

eyezen,
The shot, while in the air after it has left the hand, gets a chance to count whether, or not, the horn goes off and/or the light comes on.
Yes, the officials were looking to make sure the shot was in the air <U>and</U> off the hand.

Yes I understand that. My question is to the post above me.

quote Mark Dexter:

Is he refering to the clock stopping when the ball goes in under a minute in the second half?

If so, I'm saying that the clock runs out while the ball is in flight.

Maybe I'm missing something? I was confused by this statement and what rule he was refering to.

eyezen,
Dexter is warped half the time. Wry, dry wit escapes me often. :cool:
Maybe he'll explain.
You may be right about him ...thinking NCAA, but also there's that 0.3 tip thing that we'd have to call with 0.00 showing on the clock. ...A tough call! :)
mick

BTW, if you click quote under the post you wanna answer, that post comes up on your response. If you click add reply you come up with a clean slate.

I'm the one who was missing something (called a brain). Yes - clock can expire while in flight, and game is over. If you clearly saw the ball through the basket before the time expired, then you have to have a reset.

Hmmmmm - interesting. I think I asked about this several years ago (clock starts running at 5.0, you see the shot taken at 0.2) and the decision was that it was legal. The whole 0.3 refers to how much time A1 needs to control it, not how much to let go. (If he releases at 0.2, he must have started his shot before then.)

What I'm not sure on is if either replay system (NBA/NCAA) allows the crew chief/ref to decide on tap/try along with whether or not the ball was released before time expired. Anyone want to take a stab on this part?

I thought that was the speed of light and that electricity took the local "bus"

Mick was actually pretty accurate. The speed of light is approx. 186,000mps, but they have electrical pulses that approach that speed now.

I couldn't get your link to work but Mick's answer is incomplete. The speed of light is 186,000 mps (about 1 ft per second) through a vacuum. Electrical signals do not travel through a vacuum, they travel through conductors that are surrounded by insulators (dielectric). In the most commonly used cicuit boards signals propogate at about one half that speed, .5 ft per second which is the same way as saying it takes 2 additional nanoseconds for the signal to travel for every foot of conductor on a reasonably manufactured circuit board. It's much slower per foot if we're talking about cables surrounded by air, which is what we're talking about when we connect a control board to a horn, scoreboard and lights in a basketball arena.

Ok, I know I'm missing something here, but how does 186,000 miles per second equal 1 foot per second? :confused:
