Two shot foul or on the floor
 

Player A drives to the basket for layup. After the ball is released and before Player A's feet touch the floor, Player B gives a slight nudge both Player A and Player B fall to the floor. The basket is no good. Is it safe to say that is a two shot foul because Player A's plane was broken and was not allowed to complete his descent back to the floor?

Never "On the floor". Either shooting or non shooting foul. This would be two shots, because he is a shooter until he comes back to the floor.

He's an airborne shooter until when?

Until he returns to the floor

If Player A returns
 

If Player A returns to the floor after the shot and immediately is nudged, this would be a non shooting foul?

Correct, though Mutant would incorrectly disagree

Correct... and if in doubt, the shooter was still airborne when the foul occurred.

What's On The Floor ???
 

Things Officials Should Probably Not Be Saying In A Game

Calvin Coolidge once said, "The things I did not say never hurt me." Of course, he was not talking about basketball, but many officials would be smart to heed his sage advice as they communicate with coaches, and players.

Good communication skills are important tools to have on any official’s tool belt. Good communication with a partner, with a player, or with a coach, can go a long way to maintaining control of the game, having good game management, and having a smooth game. Sometimes this communication takes place in oral form, talking to players, or coaches, in some cases to explain a ruling, or in other cases to prevent a violation, or a foul. However, probably for reasons of tradition, there have been things that officials often, or sometimes, say during a game that do not have any basis in the rules, and should probably not be said in a game. This article will cover some of those “best left unsaid” statements.

...

"On the floor”, sometimes stated by officials for fouls against players who are not in the act of shooting, is also not rule based. This implies that a player cannot be on the floor, and shooting, at the same time, when in reality the old fashioned set shot, still used by some three point shooters, is a classic example of a player, on the floor, who is also in the act of shooting. Better statement: “No shot”.

Finally, a thought by Will Rogers, “Never miss a good chance to shut up.”

Just because I'm nosey, are you a new official or a player/coach trying to get a better grasp of the rules?
