Transition defense gets drilled as punishment, so nobody improves at it

Sprinting back is treated as a character test rather than a set of decisions, which is why it stays broken for whole seasons.

Somebody leaks out, the other team scores, and the coach blows the whistle for a sprint. Everybody runs baseline to baseline. The message is effort. The lesson is nothing.

Transition defense is a coordination problem dressed up as a motivation problem, and treating it as motivation is why so many teams are bad at it for years at a time. Getting back is the easy part. The hard part is who takes the ball, who takes the first rim runner, who has the corner, and how those assignments swap when the numbers change halfway down the floor. That is a set of reads made at full speed with incomplete information, and it deserves to be coached the way a pick and roll coverage is coached.

Almost nowhere does it get that. Practice time is finite and offense sells tickets. So transition defense becomes a slogan on a whiteboard, plus conditioning as consequence.

Build it properly and it looks like this. Four against five going the other way, with the fifth defender starting from the offensive glass so the recovery is real. Repeat with three against four. Change who is trailing. Make the guard who took the shot the one who has to make the first decision on the way back, because that is exactly the situation nobody rehearses and exactly the situation that produces open corner threes.

The uncomfortable part is that this requires admitting your best offensive rebounder is creating the problem. Crashing the glass and getting back are in direct conflict, and most staffs never state the rule clearly, which leaves five players guessing. Guessing at a sprint is how you end up with two men on the ball and nobody at the rim.

Say the rule. Two crash, three back, and the two are named. Then drill the version where somebody gets it wrong, because they will.

If your only intervention is a conditioning drill after a bad quarter, you have told the team that the problem is that they do not care. They do care. They do not know who has the ball.
