There are two teams
They line up in a straight line alternating spots
Each player tips the ball off the backboard and goes to the back of the line
When the coach blows his whistle, whoever has the ball is on offense and they fast break down to the other end of the floor vs. the defense
This drill works both on transition defense and transition offense
A coach can change the number of players that touch the baseline presenting different disadvantages for the defense
Keep score and play competitively
You can also do this drill 4 on 4 or 3 on 3
Work on transition defense coverages
