1 passes to 4 then cuts to opposite corner off back-screen set by 5. After screening, 5 steps to ball for catch as 2 sets defender up for back-door cut.

If 2 doesn't have back-door catch, 4 plays fake hand-off with 5 and then sets down-screen for 2. The read is for 4 to slip and catch quick bounce pass from 5 for lay-up as X4 is probably trailing and ready to show on downscreen for 2. 1 flares for 3 weakside to help keep defense honest.
