No Five Seconds?

[Amesman]

Coming from the naivete section of the nosebleed section of the stands ... is there no closely-guarded 5 seconds call in the NBA? At the ends of some of these playoff games, guys are holding the ball with someone pressed against them and the clock ticking waaaay down.

Is the 24-second clock is the driver here, or is it because it's simply become so customary, nobody's going to blow a whistle if, say, LeBron simply holds the ball in outstretched arm for 15 seconds while a much smaller player reaches in vain but doesn't want to commit a foul. No doubt it gets the whistle in NFHS.
