You're leaving out the concept of expected value, which is the result times the odds that it occurs.

Let's just say, for argument's sake, that the success rate of a 60 foot heave is 10%. The expected points in that scenario is .1*3, or .3 points. Similarly, let's say that a 25 foot shot goes in 25% of the time. That means that the expected points are .25*3, or .75 points. In other words, buy making the free throw, you're more than doubling your opponent's opportunity to have a successful outcome, which in this case would have been overtime, which gives you multiple chances NOT to win.

Add to this that by missing the freethrow, you're REDUCING the chances of a heave-ho from occurring. Say, for example, that you have only a 25% chance of rebounding the missed free throw. Then that makes the heave-ho's expected points .75*.1*3, or .225 expected points, which is gives your opponent less than a third of the chances of being successful in that situation.

I think they only had BZ at the line, but some other guys on that side of the court to slow down the advancement of the ball. I personally do not think it was a bad call.

so you're just assuming they complete the 3 quarters court pass? how convenient.

more like 1% if no one is there to rebound.

A 60 foot shot has a smaller chance of going in than a 25-30 foot shot does, which makes the decision the correct one, percentage wise.

You need to realize that it was a 45 foot shot, not a 60 foot shot. And assuming that Butler would get a 25-30 foot shot in that situation is just foolish. They probably get the EXACT same shot that they got except it would be to tie and not to win.

There is no justification for missing the 2nd free throw on purpose. It was the wrong decision.

im going to have to agree. no way they should have missed on purpose. would have been awesome had the heave gone in.

another consideration is there is a really good chance that Zoubek would have missed anyway....... he shoots a pretty bad percentage doesn't he. With Duke's defense ready to defend a last gasp effort to run up the court without any sort of play, they had an advantage.

That still has a higher chance of converting than a three quarters court shot...

Bottom line is that if you throw in all of the variables, it was the correct decision.

3 quarters court short? did you watch the game? its not like there was 1 second on the clock.

No, they don't. They can set a screen and get a much better look. Again, if you look at all of the odds involved, Duke made the correct decision when you look at it, even if it only gives them an edge of less than 5%.

It wasn't a 3-quarter court shot. He shot the ball from about 5 feet past halfcourt.

If Zoubek makes the free throw, Butler has to inbound and therefor can run a play. When he misses, Butler has to get the rebound, gather the ball, and then push it up the court all with the clock going. There was no time to call a play, they just had to do what they did. If Duke KNOWS that is what they will have to do, they have an advantage by defending for that.

Teams NEVER get a good shot in that situation. They always end up passing to a guard in the back court running horizontally and he shoots a 40 footer on the run. That happens most of the time even WHEN they have just called a timeout.

No they didn't. You are making a terrible assumption that they would have gotten a good look off of the inbound play. Turn on the TV right now. Every analyst they have had on is saying it is the wrong decision. And all of these analysts are former players and coaches. Coach K is an outstanding coach, but he is not perfect.

I think it was the wrong decision too

if they make the free throw then time stops and Butler runs a set play to get a desperation 3 point shot... to tie

if they miss it then Butler gets it and tries a desperation 3 point shot... but to win

I can see people arguing you don't let time stop and Butler run a play of some sort but Duke had size over these guys and would have a better shot of preventing even a successful attempt being made... or barring that foul before they can make an attempt (in this case they get 2 free throws for a 3 point deficit... Duke wins no matter what)

Judgment call without a definitively right answer... but I see more ways you win and prevent Butler from even having a chance if you make the free throw

You need to ignore the outcome and examine the decision making process when analyzing this.

The thought process is this:

-more time runs off the clock
-Butler has no time for a set play
-Butler would have a tougher shot (BTW, it is not expected that they would get that far up court in that situation...)
-Butler may not have the opportunity to take the shot if you somehow get the rebound

When you take those things into consideration, it was the correct decision. Hell, if the shot had gone in, I would still defend it as the correct decision. And if he made the free throw an they lost in overtime, then you guys would be screaming that they should have missed on purpose...

In decision analysis, what matters is getting the correct PROCESS instead of focusing on the OUTCOME. You can have a good process and a bad outcome, just as you can have a bad process and a good outcome. But when you play the percentages, over time, you will be successful more often than not by going by the better process, and in this case, missing the free throw was the best process.

Anyone who argues against the choice to miss is already ignoring the outcome and debating the decision making process

The biggest single difference is if you make it then you pretty much can't lose... if you miss it then you can lose

You can lose in overtime if you make it, and one could argue that you have a better chance of losing in OT than you do of them making the shot to try to beat you in regulation.
