There's a great article J.J. Redick via CoachingClipboard.org. It’s well worth reading in its entirety here.
The piece talks about Redick’s off-season shooting program:
◄Full speed perimeter shuttles into 140 spot up two-pointers
◄Full speed perimeter shuttles into 140 spot up three-pointers
•Must make 20 shots at seven difference spots
◄42 pull-up jumpers off the dribble
•21 to the right...21 to the left
◄20 free throws
Coaching Clipboard points out that Redick can be a perfectionist.
“It’s more OCD. I’m pretty obsessive about things,” Redick said. He expects himself to shoot 80 to 90 percent in the Sunday drill, no excuses. “I don’t take a shot unless I expect to make it. I expect to make every shot I take.”
It was also pointed out that once Redick starts these workouts in July, he goes six days a week and does not travel -- that commitment.
