"he's popping the ball up and rolling over too much."

One response: "probably need to get those hips and shoulders opening much faster"

And how to do this?

Answer: "A signal from the brain."

I think it should be pointed out that generally rolling over will cause ground balls but popups will be caused by something else. Therefore in my opinion opening the hips and shoulders faster is not the appropriate solution to the problem as described by the questioner.
