These are some notes from Chris Mack, Head Men’s Coach at the University of Louisville, and the former head coach at Xavier University.

The record by a Xavier Player is 228 by Trevon Bluiett.
The rules for the drill are as follows:
Start at spot #1.
The first 3 made shots at each spot are worth 0 (nothing) points.
Every make after the 3rd make at each spot counts as 1 point.
After a shooter misses for a 3rd time at a spot, they move to the next numbered spot.
Procedure is repeated for all 9 spots.
Score is total points from all 9 spots.
I like the unique scoring approach for this drill to add some variety to the drills you use.
You can adapt the scoring system or the number of spots for your needs.
