Applying principles of the run-and jump defense out of a halfcourt man-to-man defense offers many of the advantages as a fullcourt run and jump In a halfcourt defensive set, with one key difference:

In a halfcourt set, the defense doesn’t have the same opportunity to force the uncontrolled dribble as it does in the fullcourt - there isn’t enough space

Still, the main feature of the run and jump - springing unexpected traps out of a man to man alignment - is just as effective at forcing turnovers and, more importantly, putting the opponent on their heels. Well-timed traps force the offense to think (about whether or not a trap is coming) rather than play, disrupting offensive timing that is critical to execution. The psychological advantage that comes with forcing the offense into a herky-jerky type of rhythm can be huge, and will often lead to situations where the offense not only stops attacking, it starts making mistakes for the defense. I call theses anticipation errors.

If I’m on the other side of the ball, my approach is to attack the defense. This doesn’t mean to play dumb or to lose control - I don’t want kids trying to barrel through traps. It does mean that if we reverse the ball out of that trap, the defense had better have it’s seat belts fastened, because we’re probably going to be focused on the getting to the rim.

The first approach for implementing run and jump principles in the halfcourt is to trap down by following the entry pass (down towards the baseline).
Off-ball defenders again use zone trap/gapping principles against the 4 off-ball defenders.
Again, if the offense is able t5o complete the pass out of the trap, the defense usually goes back into its standard man to man defense. (Great BIG hint: conversion is usually the most overlooked piece of any defensive approach). If the offense does complete the pass out, the defense is forced to convert into something else - its regular man to man . This is when the defense is most likely to be disorganized, in the same way that transition defense can be disorganized. This is why we want our offense to look to attack the defense on the pass out of the trap - the turn the tables and put the defense on its heels.

Still, this approach can be very effective when used in spots. The two biggest reasons:

If the defense does get the steal, it usually occurs at the top of the key, giving the defense a breakaway layup.
Motion offenses are so common that “pass and screen-away” or “pass and cut” are commonplace - and players often execute them out of habit. Trapping down exploits this tendency by design, since an automatic pass and screen away leaves the most open area to pass to out of the trap vacant.

Run and Jump Recommendation: Dean Smith Encyclopedia of the Run and Jump

I’ve always found Dean Smith’s materials dood for getting the big picture - he was a great teacher of multiple defenses - and thisa video gives a glimpse into NC’s system and the Run and Jump.

If you’re looking to get down and dirty and really teach the run and jump or scramble defense, then Jim Larranaga’s materials are far and away the better resource.

*For any basketball gods listening, that wasn’t a knock on Dean Smith. I don’t need the bad luck that probably comes with that kind of basketball blasphemy.

Here’s a look at a successful ‘trapping down” sequence that illistrates the effectiveness of run and jump/scramble principles against unaware motion offenses:
