Took a quick look at the play by play. Relying on Torvik's possession count for the game, there were a total of 83 possessions.
With 4:00 to go, WF led 72-57, and there had been 68 possessions for the game. WF's net efficiency was +22 points per 100 possessions.
With 0:52 to go, just after a long 3 by Love and 2 FT's by Ty, WF led 85-75 and there had been 78 possessions for the game. WF's net efficiency was +12.8 points per 100 possessions.
There were 5 possessions for each team in the final 0:52. UNC outscored us 10-7. At the buzzer, there were 83 possessions, WF won 92-85, for a net efficiency of +8.4 points per 100 possessions.
Over the final 4:00, UNC scored 28 points in 15 possessions, (luckily, WF did not turn the ball over more than once, and Ty made most of his FT's) and the number of possessions in the game exploded, both of which pretty significantly supressed the value of the win in the metrics.
