Set like Space 1...

2nd OPTION of Space when 5 receives the ball from 1.

1 screens away for 4; 4 cuts to ball-side.
3 cuts through, looking for a hand-off from 5.
5 should look for an 1-on-1 option.

If 5 could not score, 2, 4 and 5 are set in a triangle with different options.
e.g. :
2 screens for 4.

If nobody gets open in scoring position, 5 passes out to 4 and he swings the ball to the other side to 1.

1 and 3 now have a two man game option on ball-side while 2,4 and 4 are running FLEX.
