In practicing the Triple Option with all six skill positions, the coaches serve as the look team. One coach is #1, one coach is #2, two other coaches rotate as #3 and the Deep Defender.
#1 and #2 keep giving the Quarterback blood stunts and easy stunts.
The other two coaches keep giving different looks. These looks include #3 as an overhang, both coaches aligning equidistant while one runs into the alley and the other drops over the top of the Receiver (Sky/Cloud), #3 as a press corner (Cover 2), and #3 in the middle of the field (Load).
Each player has a responsibility and they must technique their assignment versus these multiple situations.
Here is the Triple Drill in action.
