UNC ends the game with a traditional line-up

Hubert Davis implemented a four-guard starting line-up as a way to get his four best players on the court at the same time. That may work against some teams, but it was never going to work against a gigantic and athletic Duke team.
With the game decided, Hubert Davis had some time to do some full speed experimentation. The radical experiment? A traditional "two guards, two forwards, one center" line-up. With seven minutes left in the game, UNC ran out Elliot Cadeau, Seth Trimble, Cade Tyson, Drake Powell, and Jalen Washington, with Ian Jackson eventually subbing in for Trimble. Nobody would ever argue that this was North Carolina's line-up of best players, but they fit traditional basketball roles better.
They took a 27-point deficit and shrank it to to as little as 16 while outrebounding Duke 5-3. Will this window give Coach Davis pause for thought into how he attacks the rest of the season? Would more balance outweigh the lack of firepower?
These answers must reveal themselves if North Carolina is to make a run in time to make the NCAA Tournament.
