Step 1BOX (PASS ENTRY) is a dead ball set play and moves the post players to the elbows and the guards to the blocks. The play can be ran to either side and we will show the right side first.Step 2As the pass is made, the 2 cuts from the ballside block to the weakside corner. When 1 passes the ball, 4 steps up to set a backscreen for 1. This is excellent versus extreme pressure on your PG. The 5 will look for the backcut for 1.Step 3On the pass after the backscreen to the 4, the 5 will down screen the 3 and DUCKIN and folllow the ball posting up. The 3 will fill the left slot. After the backscreen, 1 will fill the corner. We are now in the 4 MAN FLEX.Step 44 MAN FLEX continuity offense
