There is no doubt in my mind that if given the minute, around 30min/game, Bynum would easily averages a double figure, 10/10. It's not too far away, as I saw him last season, especially earlier into the season. A lot of us was amazed how Bynum improves his game so quickly. He even filled the starting center role very well. In fact, even Ben Wallace gave prop to Bynum when he dropped a double figure the day we played the Chicago Bulls.
The one thing the Pacers should be worry about is his stamina. That is the one aspect that I think he needs to improve the most in order to go to the next level. And so far that is exactly what he's been working out in the offseason, improving his stamina and strength.
