I agree in one regard and disagree in another.
Agree that he needs to utilize the dribble more effectively.
Disagree on dribble-drive.
I think he needs to be able to use the dribble to get more open on 3s. Pump-fake, one dribble to the side, drill a 3. Curl around a screen, fake a 3 and dribble into space for his 3PA. That kind of thing.
The guy from Oakland is my model for optimal use of Roche. That guy never took any 2s and shot an extremely high volume of 3s, from a variety of looks. It was immensely effective because he got a wide variety of looks and they knew what he wanted to do and still had issues stopping it. And it really widens the court when you have a guy who has that kind of gravity to draw his own and help defenders to him at the 3 point line and beyond.
Any 2s Roche takes should be layups off back cuts. I want zero part of any 12-18 foot jumpers, except in emergency situations.
