Drake's jumper clearly still needs some work ... 'cause cameras have caught him airballin' yet another shot on the court -- this time in a 1-on-1 game with Tory Lanez.
The whiffed shot all went down in Miami (unclear exactly when) ... when Drake was getting in some run with his fellow rapper.
You can see in some footage of the two musicians' workout, Aubrey pulled up from deep against Lanez, shot the rock ... and then hit nothing but court.
