This is a possible quick-hitting play out of "high".

1 waves 2 through and 5 moves to the elbow, just like "high" is normally run. 5 receives the ball, but in this play, he looks low at 2. 2 appears to be cutting to the corner as always, but here, he buttonhooks back under the basket looking for a high-low feed from 5.

2 could also cut through and simply push his defender down, then seal, looking for 5's pass.
