Key questions to ponder as training camps begin this week:
Is Shaq in shape?
If O'Neal's arthritic right big toe is sound and his weight is down, he can stabilize the Lakers during the tumult surrounding Kobe Bryant.
How will Rick Carlisle differ from Isiah Thomas?
To do what Thomas couldn't—advance through the playoffs—the new Pacers coach must establish a steady rotation.
Is Vin Baker back?
The former All-Star center, 10 pounds lighter and recovering from alcoholism, could help the Celtics regain home court advantage in the East.
