Variations of the basic horns pick and roll, also see Horns Flare
See YouTube video - Horns double pick and roll and variations
a) Standard play
1 chooses a side, in this case 4 picks and rolls, 5 flashes to the top, 3 comes up about foul-line extended (X3 can't help on the roller).
Look for a high-low on a pass to 5, if X4 hedges 4 will often will be wide open.
5 can pass to 3 and follow to ballscreen, see YouTube video - Raptors horn reverse.
b) Screen away
The opposite post screens away, 3 looks for a shot or 5 getting post position inside.
d) Pistol action
1 comes off 4's screen, makes a dribble hand-off to 2, 4 rolls to the opposite block.
g) Duke (twist)
5 picks and rolls.
