cook was funny today, he went off on his own with a coach and worked on a "technique" for about 10 minutes

he stood next to a tackling dummy with his back to the guy throwing the ball. all he did for 10 minutes was to throw his elbow out quick into the dummy and knocking it down after the ball was thrown and before he caught it. or pushing off using his elbow to get separation before the ball gets there

basically, he was working on how to get away with OPI for 10 minutes
