Play 5 on 5 full court utilizing regular scoring (2's and 3's)
For a set period of time (i.e. 5:00), one team is always on offense and their opponent is always on defense
When a team scores on one end of the floor they grab the ball and play offense going down to the other end of the floor as well (same goes for the defense)
After time expires, switch who is on offense and who is on defense and play another round
Work on a variety of different points of emphasis depending on what your team needs or what the scouting report is.
