Duke opens big lead then holds off Carolina for 87-83 win in Chapel Hill Tuesday night.

Give the Heels credit for coming back, but why, oh why, did Carolina's Danny Green drive the basketball in the final seconds with his team down three?

Boston College did the same thing against Duke. The ACC Nation's Chris Graham would argue that it was a good move in that instance because the refs should have called a foul on Shelden Williams and given BC a chance to convert a three-point play.

But that's taking a big chance. If a team's down by three with under 10 seconds left they have to take a three-point shot. They have to. Green didn't.

He's a freshman, so maybe that explains it. But players need to be more aware of the situation. Green wasn't and it might have cost Carolina the game.
