Trent Tucker Rule (trent tuk'-uhr rool) noun. The NBA rule that disallows any standard shot (specifically a "catch and shoot" attempt) to be taken if the ball is put into play with less than three-tenths of a second left on the game clock.
Usage example:There's only one-tenth of a second left. According to the Trent Tucker Rule, that means there isn't enough time left to catch the ball and shoot it.
Word history: Most astute NBA fans are aware of this rule, but there are still plenty of people who don't know why it was originally created. The rule was conceived (although nobody knew it at the time) on January 15, 1990 during a game between the Chicago Bulls and New York Knicks at Madison Square Garden. The score was tied at 106 with one-tenth of a second left in regulation and the Knicks had possession of the ball. During a time-out called by the Knicks, both teams prepared for the (seemingly) inevitable final play: An alley-oop lob pass to Patrick Ewing.
Knicks coach Stu Jackson designed the play so that Trent Tucker would act as a decoy to draw Michael Jordan out to the perimeter and open up a lane for Patrick Ewing to receive the pass. But according to Tucker: "Michael read the play, which took away our number one option. We really didn't have a number two option because we were (only) one-tenth of a second, and we didn't have a lot of time."
When play resumed, Mark Jackson -- who was inbounding the ball for New York -- saw that the Bulls had the play covered, so he inbounded the ball to Tucker, the only open player. Tucker turned and hit a three-pointer at the buzzer, propelling the Knicks to a 109-106 victory. This is how Tucker described the final play: "Mark gave me a flip, and I shot the ball as quickly as I could. Scottie Pippen's hand met my hand as the ball left. When it went in, the Garden went crazy and we took off of the court. Phil Jackson (the Bulls' coach) was waving, 'No way, no basket.' We ran to the locker room, undressed as quickly as we could and got into the shower to make sure that they (the officials) wouldn't call us back on the floor. In our minds, the game is over."
It wasn't over for the Bulls, though. Phil Jackson, typically, was incensed. He argued vehemently that it was impossible to get a shot off in that amount of time. "A second or two, maybe. But in one-tenth of a second it can't be done. You can't shoot a shot in that time. The officials are still getting adjusted to the tenths of a second.'' Then, in true Zing Master style, he put in a final jab: "It was a judgment call. They just got a friendly call and let's leave it at that." Ah, the more things change, the more they don't...
Anyway, Jackson and the Bulls decided not to just "leave it at that." They filed an official protest with the NBA -- which cost them $1,500, by the way -- in an attempt to have the shot overturned. Had they won the protest, the teams would have had to replay the final tenth of a second and (if necessary) play one or more overtime periods to conclude the game.
It didn't matter. NBA commissioner David Stern denied their appeal. (Come on...he's always been a New York guy!) Stern admitted that Tucker's shot came well after time had expired but said that, according to league rules, the commissioner can uphold a protest only in cases in which a playing rule has been violated or misapplied. But in the case of the game in question, Stern "pointed out with legalistic exactitude" that no rules were violated; the officials simply started the clock too late, giving Tucker the time he needed to attempt the shot.
Said the Commish: "The question before me is not whether Trent Tucker received Mark Jackson's pass and released his shot within one-tenth of second. Plainly, he did not. The question presented by Chicago's protest, rather, is whether the referees' failure to disallow Tucker's shot constitutes a sufficient basis for overturning the result of the game. The NBA has consistently denied protest based on errors in judgment by the game officials." Again, the more things change, the more they don't...
Even though he slapped down the Bulls' protest, Stern announced that from that point forward, if the ball is put into play with less than three-tenths of a second on the clock, "any shot other than a tip-in or an alley-oop must be disallowed." And thus the Trent Tucker Rule was born.
But the new rule could not erase Tucker's accomplishment. Or his joy over it. "It's the greatest shot I ever made. I just caught the ball and flung it. When the ball left my hands, I knew it was on target. What I didn't know was whether it had the distance. When it went in, I thought to myself, 'not bad for a guy who was supposed to be a decoy on the play."
Further reading:The official NBA rulebook states that: "NO LESS THAN :00.3 must expire on the game clock when a player secures possession of an inbounds pass and then attempts a field goal. If less than :00.3 expires in such a situation, the timer will be instructed to deduct AT LEAST :00.3 from the game clock. If less than :00.3 remain on the game clock when this situation occurs, the period is over, and the field goal attempt will be disallowed immediately whether successful or unsuccessful."

Update! Mighty Science, with help from Jason Kapono and his beautiful hair, has proven that it is in fact possible to catch and shoot with less than three-tenths of a second. And here's the video to prove it. (But don't expect a rule change any time soon.) Thanks to Basketbawful reader herman for the link.
